In 1969, Yorba Linda -born Orange County native Richard Nixon became the 37th President of the United States . He established a " Western White House " in San Clemente , in South Orange County, known as La Casa Pacifica , and visited throughout his presidency. In
471-455: A conductor 's surface, since otherwise there would be a force along the surface of the conductor that would move the charge carriers to even the potential across the surface. The electric field was formally defined as the force exerted per unit charge, but the concept of potential allows for a more useful and equivalent definition: the electric field is the local gradient of the electric potential. Usually expressed in volts per metre,
628-461: A force on each other, an effect that was known, though not understood, in antiquity. A lightweight ball suspended by a fine thread can be charged by touching it with a glass rod that has itself been charged by rubbing with a cloth. If a similar ball is charged by the same glass rod, it is found to repel the first: the charge acts to force the two balls apart. Two balls that are charged with a rubbed amber rod also repel each other. However, if one ball
785-409: A steady state current, but instead blocks it. The inductor is a conductor, usually a coil of wire, that stores energy in a magnetic field in response to the current through it. When the current changes, the magnetic field does too, inducing a voltage between the ends of the conductor. The induced voltage is proportional to the time rate of change of the current. The constant of proportionality
942-755: A "downtown for Orange County". The 820 acres (330 ha) area undergoing this large-scale redevelopment includes the city's two major sports venues, the Honda Center and Angel Stadium of Anaheim . The 2010 United States Census reported that Orange County had a population of 3,010,232. The racial makeup of Orange County was 1,830,758 (60.8%) White (44.0% non-Hispanic white), 50,744 (1.7%) African American , 18,132 (0.6%) Native American , 537,804 (17.9%) Asian , 9,354 (0.3%) Pacific Islander , 435,641 (14.5%) from other races , and 127,799 (4.2%) from two or more races. Hispanic or Latino of any race were 1,012,973 persons (33.7%). The Hispanic and Latino population
1099-456: A central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing with electrical circuits involving active components such as vacuum tubes , transistors , diodes and integrated circuits , and associated passive interconnection technologies. The study of electrical phenomena dates back to antiquity, with theoretical understanding progressing slowly until

Electricity is usually sold by the kilowatt hour (3.6 MJ) which is the product of power in kilowatts multiplied by running time in hours. Electric utilities measure power using electricity meters , which keep
1413-512: A common reference point to which potentials may be expressed and compared is useful. While this could be at infinity, a much more useful reference is the Earth itself, which is assumed to be at the same potential everywhere. This reference point naturally takes the name earth or ground . Earth is assumed to be an infinite source of equal amounts of positive and negative charge and is therefore electrically uncharged—and unchargeable. Electric potential
1570-468: A current of one amp. The capacitor is a development of the Leyden jar and is a device that can store charge, and thereby storing electrical energy in the resulting field. It consists of two conducting plates separated by a thin insulating dielectric layer; in practice, thin metal foils are coiled together, increasing the surface area per unit volume and therefore the capacitance . The unit of capacitance
1727-490: A dampened kite string and flown the kite in a storm-threatened sky . A succession of sparks jumping from the key to the back of his hand showed that lightning was indeed electrical in nature. He also explained the apparently paradoxical behavior of the Leyden jar as a device for storing large amounts of electrical charge in terms of electricity consisting of both positive and negative charges. In 1775, Hugh Williamson reported

#17328443117231884-425: A large lightning cloud may be as high as 100 MV and have discharge energies as great as 250 kWh. The field strength is greatly affected by nearby conducting objects, and it is particularly intense when it is forced to curve around sharply pointed objects. This principle is exploited in the lightning conductor , the sharp spike of which acts to encourage the lightning strike to develop there, rather than to
2041-599: A mall named "The City" which was the centerpiece of a planned, 1970s mixed-use development by the same name. There is commercial strip-style development including big box retailers along West Chapman Avenue in Orange, along Harbor Boulevard in Garden Grove, and around Harbor Boulevard and Chapman Avenue in Anaheim. Major hotels line Harbor Boulevard from Disneyland south to Garden Grove. The Orange County Transit Authority studied
2198-402: A millimetre per second, the electric field that drives them itself propagates at close to the speed of light , enabling electrical signals to pass rapidly along wires. Current causes several observable effects, which historically were the means of recognising its presence. That water could be decomposed by the current from a voltaic pile was discovered by Nicholson and Carlisle in 1800,
2355-553: A more reliable source of electrical energy than the electrostatic machines previously used. The recognition of electromagnetism , the unity of electric and magnetic phenomena, is due to Hans Christian Ørsted and André-Marie Ampère in 1819–1820. Michael Faraday invented the electric motor in 1821, and Georg Ohm mathematically analysed the electrical circuit in 1827. Electricity and magnetism (and light) were definitively linked by James Clerk Maxwell , in particular in his " On Physical Lines of Force " in 1861 and 1862. While
2512-485: A municipal general plan in 1972. By the 1980 Census , the population was nearing 30,000. Within ten years it exceeded 50,000. In 1990, the Richard Nixon Presidential Library and Museum opened as a privately owned, public museum and research library with ceremonies that included a joint appearance by Presidents Richard Nixon, Gerald Ford , Ronald Reagan and George H.W. Bush . The campus included
2669-531: A nation which "extended from Palos Verdes to San Bernardino, from Saddleback Mountain to the San Fernando Valley" and included the entire territory of present-day Yorba Linda. Spanish colonization between 1769 and 1840 brought "disease, invasive species, and livestock" into the area, which "upended the ecological balance of the region and forced the Tongva to resettle around three missions." The village of Hutuknga
2826-467: A new county to be named "Orange" as directed by the legislature. The referendum required a 2/3 vote for secession to take place, and on June 4, 1889, the vote was 2,509 to 500 in favor of secession. After the referendum, Los Angeles County filed three lawsuits to prevent the secession, but their attempts were futile. On July 17, 1889, a second referendum was held south of the Coyote Creek to determine if
2983-688: A population exceeding 300,000. Santa Ana is also the county seat . Six cities in Orange County are on the Pacific coast: Seal Beach , Huntington Beach , Newport Beach , Laguna Beach , Dana Point , and San Clemente . Orange County is included in the Los Angeles–Long Beach–Anaheim Metropolitan Statistical Area . The county has 34 incorporated cities. Older cities like Tustin , Santa Ana, Anaheim, Orange , and Fullerton have traditional downtowns dating back to
3140-425: A positive current is defined as having the same direction of flow as any positive charge it contains, or to flow from the most positive part of a circuit to the most negative part. Current defined in this manner is called conventional current . The motion of negatively charged electrons around an electric circuit , one of the most familiar forms of current, is thus deemed positive in the opposite direction to that of
3297-420: A positive or negative electric charge produces an electric field . The motion of electric charges is an electric current and produces a magnetic field . In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the work done to move an electric charge from one point to another within an electric field, typically measured in volts . Electricity plays

#17328443117233454-891: A practical generator, but it showed the possibility of generating electric power using magnetism, a possibility that would be taken up by those that followed on from his work. An electric circuit is an interconnection of electric components such that electric charge is made to flow along a closed path (a circuit), usually to perform some useful task. The components in an electric circuit can take many forms, which can include elements such as resistors , capacitors , switches , transformers and electronics . Electronic circuits contain active components , usually semiconductors , and typically exhibit non-linear behaviour, requiring complex analysis. The simplest electric components are those that are termed passive and linear : while they may temporarily store energy, they contain no sources of it, and exhibit linear responses to stimuli. The resistor
3611-406: A process now known as electrolysis . Their work was greatly expanded upon by Michael Faraday in 1833. Current through a resistance causes localised heating, an effect James Prescott Joule studied mathematically in 1840. One of the most important discoveries relating to current was made accidentally by Hans Christian Ørsted in 1820, when, while preparing a lecture, he witnessed the current in
3768-471: A rapidly changing one. Electric power is the rate at which electric energy is transferred by an electric circuit . The SI unit of power is the watt , one joule per second . Electric power, like mechanical power , is the rate of doing work , measured in watts , and represented by the letter P . The term wattage is used colloquially to mean "electric power in watts." The electric power in watts produced by an electric current I consisting of
3925-485: A resistance is directly proportional to the potential difference across it. The resistance of most materials is relatively constant over a range of temperatures and currents; materials under these conditions are known as 'ohmic'. The ohm , the unit of resistance, was named in honour of Georg Ohm , and is symbolised by the Greek letter Ω. 1 Ω is the resistance that will produce a potential difference of one volt in response to
4082-595: A running total of the electric energy delivered to a customer. Unlike fossil fuels , electricity is a low entropy form of energy and can be converted into motion or many other forms of energy with high efficiency. Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes , transistors , diodes , sensors and integrated circuits , and associated passive interconnection technologies. The nonlinear behaviour of active components and their ability to control electron flows makes digital switching possible, and electronics
4239-431: A scientific curiosity into an essential tool for modern life. In 1887, Heinrich Hertz discovered that electrodes illuminated with ultraviolet light create electric sparks more easily. In 1905, Albert Einstein published a paper that explained experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets, energising electrons. This discovery led to
4396-596: A separate district was established for the library system. In 1915, the Susanna Bixby Bryant Ranch house was constructed. It is a museum that is open to the public. In 1917, the first street was paved, Yorba Linda Boulevard. The Yorba Linda Star began publication also. It has since become an online section of the OC Register . A printed version of the Star is available at various city buildings free of charge and
4553-568: A series of experiments to the Royal Society on the shocks delivered by the electric eel ; that same year the surgeon and anatomist John Hunter described the structure of the fish's electric organs . In 1791, Luigi Galvani published his discovery of bioelectromagnetics , demonstrating that electricity was the medium by which neurons passed signals to the muscles. Alessandro Volta 's battery, or voltaic pile , of 1800, made from alternating layers of zinc and copper, provided scientists with
4710-510: A series of observations on static electricity around 600 BCE, from which he believed that friction rendered amber magnetic , in contrast to minerals such as magnetite , which needed no rubbing. Thales was incorrect in believing the attraction was due to a magnetic effect, but later science would prove a link between magnetism and electricity. According to a controversial theory, the Parthians may have had knowledge of electroplating , based on
4867-479: A significant source of sales tax revenue to Yorba Linda and as one of the first anchor tenants (along with Best Buy ), The Home Depot became a political talking point in its own right, due to the geography that divides Savi Ranch into two sections, the larger east side falling within Yorba Linda's city limits, and the west side where Home Depot is situated falling within the adjacent City of Anaheim boundaries.

5024-477: A solid crystal (such as a germanium crystal) to detect a radio signal by the contact junction effect. In a solid-state component, the current is confined to solid elements and compounds engineered specifically to switch and amplify it. Current flow can be understood in two forms: as negatively charged electrons , and as positively charged electron deficiencies called holes . These charges and holes are understood in terms of quantum physics. The building material

This group purchased a 1,165 acres (4.71 km ) parcel from Juan Pacifico Ontiveros's Rancho San Juan Cajon de Santa Ana for $ 2 per acre and later formed the Anaheim Vineyard Company . With surveyor George Hansen , two of the wine colony's founders, John Frohling and Charles Kohler, planted 400,000 grapevines along the Santa Ana River ; by 1875, "there were as many as 50 wineries in Anaheim, and
5338-641: A transition zone between north and south; when this viewpoint is taken Tustin is also considered to be in Central Orange County. Costa Mesa is sometimes included in South County, although it is located predominantly to the west of the Costa Mesa Freeway and is part of the even street grid network of northern Orange County. Irvine is located in a valley defined by the Santa Ana Mountains and
5495-511: A wire disturbing the needle of a magnetic compass. He had discovered electromagnetism , a fundamental interaction between electricity and magnetics. The level of electromagnetic emissions generated by electric arcing is high enough to produce electromagnetic interference , which can be detrimental to the workings of adjacent equipment. In engineering or household applications, current is often described as being either direct current (DC) or alternating current (AC). These terms refer to how
5652-448: A wire suspended from a pivot above the magnet and dipped into the mercury. The magnet exerted a tangential force on the wire, making it circle around the magnet for as long as the current was maintained. Experimentation by Faraday in 1831 revealed that a wire moving perpendicular to a magnetic field developed a potential difference between its ends. Further analysis of this process, known as electromagnetic induction , enabled him to state
5809-402: A wire. The informal term static electricity refers to the net presence (or 'imbalance') of charge on a body, usually caused when dissimilar materials are rubbed together, transferring charge from one to the other. Charge can be measured by a number of means, an early instrument being the gold-leaf electroscope , which although still in use for classroom demonstrations, has been superseded by
5966-584: Is a scalar quantity . That is, it has only magnitude and not direction. It may be viewed as analogous to height : just as a released object will fall through a difference in heights caused by a gravitational field, so a charge will 'fall' across the voltage caused by an electric field. As relief maps show contour lines marking points of equal height, a set of lines marking points of equal potential (known as equipotentials ) may be drawn around an electrostatically charged object. The equipotentials cross all lines of force at right angles. They must also lie parallel to
6123-411: Is a vector field . The study of electric fields created by stationary charges is called electrostatics . The field may be visualised by a set of imaginary lines whose direction at any point is the same as that of the field. This concept was introduced by Faraday, whose term ' lines of force ' still sometimes sees use. The field lines are the paths that a point positive charge would seek to make as it

6594-452: Is an important difference. Gravity always acts in attraction, drawing two masses together, while the electric field can result in either attraction or repulsion. Since large bodies such as planets generally carry no net charge, the electric field at a distance is usually zero. Thus gravity is the dominant force at distance in the universe, despite being much weaker. An electric field generally varies in space, and its strength at any one point
6751-657: Is bordered on the southwest by the Pacific Ocean , on the north by Los Angeles County , on the northeast by San Bernardino County , on the east by Riverside County , and on the southeast by San Diego County . The northwestern part of the county lies on the coastal plain of the Los Angeles Basin , while the southeastern end rises into the foothills of the Santa Ana Mountains . Most of Orange County's population reside in one of two shallow coastal valleys that lie in
6908-401: Is charged by the glass rod, and the other by an amber rod, the two balls are found to attract each other. These phenomena were investigated in the late eighteenth century by Charles-Augustin de Coulomb , who deduced that charge manifests itself in two opposing forms. This discovery led to the well-known axiom: like-charged objects repel and opposite-charged objects attract . The force acts on

According to the city's 2020 Comprehensive Annual Financial Report, the top employers in the city are: Yorba Linda was, at one point in time, California's most conservative large community, as measured by the proportion of conservative to liberal voters. Although Democrats have been making inroads in Orange County as a whole as well as the city itself, Yorba Linda
7222-468: Is defined as negative, and that by protons is positive. Before these particles were discovered, Benjamin Franklin had defined a positive charge as being the charge acquired by a glass rod when it is rubbed with a silk cloth. A proton by definition carries a charge of exactly 1.602 176 634 × 10 coulombs . This value is also defined as the elementary charge . No object can have a charge smaller than
7379-483: Is defined as the force (per unit charge) that would be felt by a stationary, negligible charge if placed at that point. The conceptual charge, termed a ' test charge ', must be vanishingly small to prevent its own electric field disturbing the main field and must also be stationary to prevent the effect of magnetic fields . As the electric field is defined in terms of force , and force is a vector , having both magnitude and direction , it follows that an electric field

In 1929, the citrus association's packing house burned down, as it was made of wood. It reopened the next year. During this period, the eastern two-thirds of Yorba Linda (east of the Yorba Linda Country Club) remained part of cattle and agricultural ranches controlled by pioneer families such as
7693-484: Is home to the county's only natural lakes, Laguna Lakes, which are formed by water rising up against an underground fault. Orange County is sometimes divided into northern and southern regions. There are significant political, demographic, economic and cultural distinctions between North and South Orange County. A popular dividing line between the two regions is the Costa Mesa Freeway . Northern Orange County, including Anaheim, Fullerton , Garden Grove and Santa Ana ,
7850-531: Is integral to applications spanning transport , heating , lighting , communications , and computation , making it the foundation of modern industrial society. Long before any knowledge of electricity existed, people were aware of shocks from electric fish . Ancient Egyptian texts dating from 2750 BCE described them as the "protectors" of all other fish. Electric fish were again reported millennia later by ancient Greek , Roman and Arabic naturalists and physicians . Several ancient writers, such as Pliny

#17328443117238164-406: Is mediated by the magnetic field each current produces and forms the basis for the international definition of the ampere . This relationship between magnetic fields and currents is extremely important, for it led to Michael Faraday's invention of the electric motor in 1821. Faraday's homopolar motor consisted of a permanent magnet sitting in a pool of mercury . A current was allowed through
8321-415: Is most often a crystalline semiconductor . Solid-state electronics came into its own with the emergence of transistor technology. The first working transistor, a germanium -based point-contact transistor , was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947, followed by the bipolar junction transistor in 1948. By modern convention, the charge carried by electrons

The village of Puhú was located in what is now Black Star Canyon and was shared by multiple groups, including the Tongva, Acjachemen, Serrano and Payómkawichum . The mother village of the Acjachemen was Putiidhem and is now located in San Juan Capistrano underneath Junipero Serra Catholic High School . For
8635-403: Is perhaps the simplest of passive circuit elements: as its name suggests, it resists the current through it, dissipating its energy as heat. The resistance is a consequence of the motion of charge through a conductor: in metals, for example, resistance is primarily due to collisions between electrons and ions. Ohm's law is a basic law of circuit theory , stating that the current passing through
8792-462: Is predominantly flat, giving way to the Santa Ana Mountains in the Northeast. Southern Orange County is wealthier, more residential, more Republican, predominantly non-Hispanic white, and more recently developed. Irvine, the largest city in the region, is an exception to some of these trends, being not only a major employment center, but also a major tech hub and education center with UCI. Furthermore,

Every GOP candidate for president since the city's incorporation in 1967 has received over 52% of the vote in the city. In 2016 , the city gave Donald Trump 59 percent of the vote and a 24-point margin of victory, despite the fact that he became the first Republican presidential nominee to lose Orange County since Alf Landon in 1936 . Yorba Linda
9420-531: Is subjected to transients , such as when first energised. The concept of the electric field was introduced by Michael Faraday . An electric field is created by a charged body in the space that surrounds it, and results in a force exerted on any other charges placed within the field. The electric field acts between two charges in a similar manner to the way that the gravitational field acts between two masses , and like it, extends towards infinity and shows an inverse square relationship with distance. However, there

In coastal villages like Lupukngna , at least 3,000 years old located in what is now Huntington Beach , villagers likely used te'aats or plank boats to navigate the coastline, with fish and shellfish being more central to the diet. In inland villages such as Hutuknga , rabbit and mule deer were more central, in addition to acorns from oak trees and seeds from grasses and sage bushes common everywhere. After
11932-423: The electromagnetic force , one of the four fundamental forces of nature. Experiment has shown charge to be a conserved quantity , that is, the net charge within an electrically isolated system will always remain constant regardless of any changes taking place within that system. Within the system, charge may be transferred between bodies, either by direct contact, or by passing along a conducting material, such as
12089-511: The quantum revolution. Einstein was awarded the Nobel Prize in Physics in 1921 for "his discovery of the law of the photoelectric effect". The photoelectric effect is also employed in photocells such as can be found in solar panels . The first solid-state device was the " cat's-whisker detector " first used in the 1900s in radio receivers. A whisker-like wire is placed lightly in contact with
12246-452: The strong interaction , but unlike that force it operates over all distances. In comparison with the much weaker gravitational force , the electromagnetic force pushing two electrons apart is 10 times that of the gravitational attraction pulling them together. Charge originates from certain types of subatomic particles , the most familiar carriers of which are the electron and proton . Electric charge gives rise to and interacts with
12403-810: The 1769 expedition of Gaspar de Portolà , a Spanish expedition led by Junipero Serra named the area Valle de Santa Ana (Valley of Saint Anne ). On November 1, 1776, Mission San Juan Capistrano became the area's first permanent European settlement. Among those who came with Portolá were José Manuel Nieto and José Antonio Yorba . Both these men were given land grants— Rancho Los Nietos and Rancho Santiago de Santa Ana , respectively. The Nieto heirs were granted land in 1834. The Nieto ranches were known as Rancho Los Alamitos , Rancho Las Bolsas , and Rancho Los Coyotes . Yorba heirs Bernardo Yorba and Teodosio Yorba were also granted Rancho Cañón de Santa Ana (Santa Ana Canyon Ranch) and Rancho Lomas de Santiago , respectively. Other ranchos in Orange County were granted by
12560-529: The 17th and 18th centuries. The development of the theory of electromagnetism in the 19th century marked significant progress, leading to electricity's industrial and residential application by electrical engineers by the century's end. This rapid expansion in electrical technology at the time was the driving force behind the Second Industrial Revolution , with electricity's versatility driving transformations in both industry and society. Electricity
12717-538: The 1936 discovery of the Baghdad Battery , which resembles a galvanic cell , though it is uncertain whether the artifact was electrical in nature. Electricity would remain little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert wrote De Magnete , in which he made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber. He coined
12874-680: The 19th century, while newer commercial development or " edge cities " stretch along the Interstate 5 (Santa Ana) Freeway between Disneyland and Santa Ana and between South Coast Plaza and the Irvine Business Complex , and cluster at Irvine Spectrum . Although single-family homes make up the dominant landscape of most of the county, northern and central Orange County is relatively more urbanized and dense as compared to those areas south of Irvine, which are less dense, though still contiguous and primarily suburban rather than exurban . The county
13031-509: The Asian population, 6.1% are Vietnamese, followed by Koreans (2.9%), Chinese (2.7%), Filipinos (2.4%), Indians (1.4%), Japanese (1.1%), Cambodians (0.2%), Pakistanis (0.2%), Thais (0.1%), Indonesians (0.1%), and Laotians (0.1%). According to KPCC in 2014, Orange County has the largest proportion of Asian Americans in Southern California, where one in five residents are Asian American. There
13188-645: The Elder and Scribonius Largus , attested to the numbing effect of electric shocks delivered by electric catfish and electric rays , and knew that such shocks could travel along conducting objects. Patients with ailments such as gout or headache were directed to touch electric fish in the hope that the powerful jolt might cure them. Ancient cultures around the Mediterranean knew that certain objects, such as rods of amber , could be rubbed with cat's fur to attract light objects like feathers. Thales of Miletus made

Entertainment and cultural facilities include Disneyland Resort , Angel Stadium , Christ Cathedral (formerly Crystal Cathedral), City National Grove of Anaheim – a live concert venue, Discovery Cube Orange County ,
13502-675: The Mendez family were denied enrollment into the 17th Street School in Westminster in 1944, despite their cousins with lighter skin being admitted, and were instead told to enroll at the Hoover Elementary School for Mexican children. In the 1950s, agriculture, such as that involving the boysenberries made famous by Buena Park native Walter Knott , began to decline. However, the county's prosperity soared during this time. The completion of Interstate 5 in 1954 helped make Orange County
13659-593: The Mexican government during the Mexican period in Alta California . Saint Junípero Serra y Ferrer and the early components of the Portolá Expedition arrived in modern-day San Diego , south of present-day Orange County, in mid-late 1769. During these early Mission years, however, the early immigrants continued to rely on imports of both Mexican-grown and Spanish-grown wines; Serra repeatedly complained of
13816-529: The Pacific Electric and nephew of Collis Huntington . Transportation further improved with the completion of the State Route and U.S. Route 101 (now mostly Interstate 5 ) in the 1920s. In the 1910s, agriculture in Orange County was largely centered on grains, hay, and potatoes by small farmers, accounting for 60% of the county's exports. The Segerstroms and Irvines once produced so many lima beans that
13973-449: The Yorba, de los Reyes, Kraemer, Travis, Dominguez, Friend, and Bryant ranches. From 1943 to 1958, "approximately seventy thousand braceros were transported to Orange County," used by employers to service citrus crops. Braceros lived in temporary housing projects referred to as "camps," which were policed by local deputies throughout the county. The townspeople of Yorba Linda "refused to allow
14130-551: The agricultural aspect of that endeavor materialized, and the first of many lemon and orange groves were planted: at the time, the population was still less than 50. A year later, The Pacific Telephone & Telegraph Company began serving Yorba Linda, and the first school was constructed. In 1912, several things happened in Yorba Linda: it received its first post office ; the Yorba Linda Citrus Association
14287-402: The average family size was 3.35. In the city, 29.3% of the population was under the age of 18, 7.3% was from 18 to 24, 28.4% from 25 to 44, 27.3% from 45 to 64, and 7.7% was 65 years of age or older. The median age was 37 years. For every 100 females, there were 96.6 males. For every 100 females age 18 and over, there were 93.1 males. According to a 2007 estimate, the median household income in
14444-624: The basin, the Santa Ana Valley and the Saddleback Valley . The Santa Ana Mountains lie within the eastern boundaries of the county and of the Cleveland National Forest . The high point is Santiago Peak (5,689 ft (1,734 m) ), about 20 mi (32 km) east of Santa Ana. Santiago Peak and nearby Modjeska Peak , just 200 ft (60 m) shorter, form a ridge known as Saddleback , visible from almost everywhere in
14601-408: The beginning of the field theory of the electric force. Further work was conducted in the 17th and early 18th centuries by Otto von Guericke , Robert Boyle , Stephen Gray and C. F. du Fay . Later in the 18th century, Benjamin Franklin conducted extensive research in electricity, selling his possessions to fund his work. In June 1752 he is reputed to have attached a metal key to the bottom of
14758-419: The building it serves to protect. The concept of electric potential is closely linked to that of the electric field. A small charge placed within an electric field experiences a force, and to have brought that charge to that point against the force requires work . The electric potential at any point is defined as the energy required to bring a unit test charge from an infinite distance slowly to that point. It
14915-426: The charged particles themselves, hence charge has a tendency to spread itself as evenly as possible over a conducting surface. The magnitude of the electromagnetic force, whether attractive or repulsive, is given by Coulomb's law , which relates the force to the product of the charges and has an inverse-square relation to the distance between them. The electromagnetic force is very strong, second only in strength to
15072-450: The charged parts. Air, for example, tends to arc across small gaps at electric field strengths which exceed 30 kV per centimetre. Over larger gaps, its breakdown strength is weaker, perhaps 1 kV per centimetre. The most visible natural occurrence of this is lightning , caused when charge becomes separated in the clouds by rising columns of air, and raises the electric field in the air to greater than it can withstand. The voltage of
15229-403: The city is an Asian plurality (both South and East Asian), and votes reliably Democratic in recent years. Southern Orange County almost always includes Irvine, Newport Beach , and the cities to their southeast, including Lake Forest , Laguna Niguel , Laguna Beach , Mission Viejo , and San Clemente . Alternatively, Irvine and Newport Beach are sometimes seen as Central Orange County, acting as
15386-413: The city of Irvine pledging to be a zero-carbon economy by 2030 and Buena Park , Huntington Beach , and Fullerton pledging to move to 100% clean energy. Residential solar panel installation has rapidly increased, even among middle-income families, as a result of the state's residential solar program which began in 2006. In the 2010s, campaigns to conserve remaining natural areas gained awareness. By
15543-460: The city pursued construction of an auto mall on the entire Savi Ranch site. The original plan was rejected by residents in favor of a combination of retail stores, restaurants, hotels, and office buildings. As of 2018, one of the three original car lots has been converted into state-mandated low-income housing, one specializes in wheelchair accessible vehicles, and the remaining car dealer, specializes in high-end, exotic, and specialty used cars. As
15700-666: The city was $ 109,681, and the median income for a family was $ 122,373. Males had a median income of $ 66,712 versus $ 41,820 for females.

Imperial Highway ( SR 90 ), Bastanchury Road, Esparanza Road, La Palma Avenue, and Yorba Linda Boulevard are west–east streets. North–south streets include Rose Drive, Fairmont Boulevard, Lakeview Avenue, Gypsum Canyon Road, Kellogg Drive, Van Buren Street, Richfield Road, and Village Center Drive. SR 241 has its northern terminus at
15857-447: The city's wine production topped 1 million gallons annually." Despite later afflictions of both Phylloxera and Pierce's Disease , wine growing is still practiced. A severe drought in the 1860s devastated the prevailing industry, cattle ranching , and much land came into the possession of Richard O'Neill Sr. James Irvine and other land barons . In 1887, silver was discovered in the Santa Ana Mountains , attracting settlers via
16014-416: The city, not including an additional 1,500 home-based businesses. The city also owns Black Gold Golf Club . Non-profit charities based in Yorba Linda include International Student Volunteers and STEMpowerment Inc. Savi Ranch is an acronym of S anta A na V alley I rrigation, an early water company. Savi Ranch today contains retailers, auto dealers, restaurants, hotels, and office buildings. Originally,
16171-489: The city. The name Yorba Linda is made up of two parts: Yorba, after Don Bernardo Yorba , a Californio ranchero who historically owned the area, and linda , Spanish for beautiful. The name was created in 1908 by the Janss Investment Company . The area is the home of the Tongva , Luiseño , and Juaneño tribal nations, who were there "as early as 4,000 years ago." The Tongva defined their world as Tovaangar ,
16328-434: The city. The population density was 3,042.3 inhabitants per square mile (1,174.6/km). There were 19,567 housing units at an average density of 1,010.4 per square mile (390.1/km). The racial makeup of the city was 81.5% White , 1.2% African American , 0.4% Native American , 11.1% Asian , 0.1% Pacific Islander , 2.7% from other races , and 3.1% from two or more races. Hispanic or Latino residents of any race were 10.3% of
16485-434: The corridor as the possible route for a streetcar, a proposal that was dropped in 2018 due to opposition from Anaheim and other city governments. In addition to suburban-style apartment complexes, Anaheim's Platinum Triangle is undergoing transformation from a low-density commercial and industrial zone into a more urban environment with high-density housing, commercial office towers, and retail space. Anaheim envisions it as
16642-460: The county has a total area of 948 sq mi (2,460 km ), of which 791 sq mi (2,050 km ) is land and 157 sq mi (410 km ) (16.6%) is water. It is the smallest county by area in Southern California , being just over 40% the size of the region's next smallest county, Ventura . The average annual temperature is about 68 °F (20 °C). Orange County
16799-534: The county seat of the new county would be Anaheim or Santa Ana, along with an election for every county officer. Santa Ana defeated Anaheim in the referendum. With the referendum having passed, the County of Orange was officially incorporated on August 1, 1889. Since the incorporation of the county, the only geographical changes made to the boundary was when the County and Los Angeles County traded some parcels of land around Coyote Creek to conform to city blocks. The county
16956-508: The county was 64.8% White , 13.6% Asian , 1.7% African American , 0.7% Native American , 0.3% Pacific Islander , 14.8% from other races , and 4.1% from two or more races. 30.8% were Hispanic or Latino of any race. 8.9% were of German , 6.9% English and 6.0% Irish ancestry according to Census 2000 . 58.6% spoke only English at home; 25.3% spoke Spanish , 4.7% Vietnamese , 1.9% Korean , 1.5% Chinese ( Cantonese or Mandarin ) and 1.2% Tagalog . Electricity Electricity
17113-548: The county was called "Beanville". By 1920, fruit and nut exports exploded, which led to the increase of industrialized farming and the decline of family farms. For example, by 1917, William Chapman came to own 350,000 acres in northeastern Orange County from the Valencia orange . Around the 1910s and 1920s, most of the barrios of Orange County, such as in Santa Ana, further developed as company towns of Mexican laborers, who worked in
17270-431: The county's shrinking natural areas. In 1994, an investment fund meltdown led to the criminal prosecution of treasurer Robert Citron . The county lost at least $ 1.5 billion through high-risk investments in bonds. The loss was blamed on derivatives by some media reports. On December 6, 1994, the County of Orange declared Chapter 9 bankruptcy, from which it emerged on June 12, 1996. The Orange County bankruptcy
17427-478: The county. The Peralta Hills extend westward from the Santa Ana Mountains through the communities of Anaheim Hills , Orange , and ending in Olive . The Loma Ridge is another prominent feature, running parallel to the Santa Ana Mountains through the central part of the county, separated from the taller mountains to the east by Santiago Canyon . The Santa Ana River is the county's principal watercourse, flowing through
17584-411: The current varies in time. Direct current, as produced by example from a battery and required by most electronic devices, is a unidirectional flow from the positive part of a circuit to the negative. If, as is most common, this flow is carried by electrons, they will be travelling in the opposite direction. Alternating current is any current that reverses direction repeatedly; almost always this takes
17741-470: The deaths disproportionately occurred in the homeless population . However, deaths were widespread among affluent and poorer areas in Orange County, with the highest at-risk group being Caucasian males between the ages of 45–55. A 2018 study found that supply reduction was not sufficient to preventing deaths. In 2008, a report issued by the Orange County Superior Court found that the county
17898-516: The design and construction of electronic circuits to solve practical problems are part of electronics engineering . Faraday's and Ampère's work showed that a time-varying magnetic field created an electric field, and a time-varying electric field created a magnetic field. Thus, when either field is changing in time, a field of the other is always induced. These variations are an electromagnetic wave . Electromagnetic waves were analysed theoretically by James Clerk Maxwell in 1864. Maxwell developed
18055-478: The early 19th century had seen rapid progress in electrical science, the late 19th century would see the greatest progress in electrical engineering . Through such people as Alexander Graham Bell , Ottó Bláthy , Thomas Edison , Galileo Ferraris , Oliver Heaviside , Ányos Jedlik , William Thomson, 1st Baron Kelvin , Charles Algernon Parsons , Werner von Siemens , Joseph Swan , Reginald Fessenden , Nikola Tesla and George Westinghouse , electricity turned from
18212-544: The early 2020s, some success was found, with the conservation of 24 acres in the West Coyote Hills of a total 510 acres and the Genga/Banning Ranch project moving forward, conserving some 385 acres, which was part of the Tongva village area of Genga . In 2021, the commemorative 1.5 acre Putuidem village opened after years of delays and campaigning by the Acjachemen . According to the U.S. Census Bureau ,
18369-527: The early economy. Orange County benefited from the July 4, 1904, completion of the Pacific Electric Railway , a trolley connecting Los Angeles with Santa Ana and Newport Beach . The link made Orange County an accessible weekend retreat for celebrities of early Hollywood . It was deemed so significant that Pacific City changed its name to Huntington Beach in honor of Henry E. Huntington , president of
18526-427: The effect was reciprocal: a current exerts a force on a magnet, and a magnetic field exerts a force on a current. The phenomenon was further investigated by Ampère , who discovered that two parallel current-carrying wires exerted a force upon each other: two wires conducting currents in the same direction are attracted to each other, while wires containing currents in opposite directions are forced apart. The interaction
18683-448: The electronic electrometer . The movement of electric charge is known as an electric current , the intensity of which is usually measured in amperes . Current can consist of any moving charged particles; most commonly these are electrons, but any charge in motion constitutes a current. Electric current can flow through some things, electrical conductors , but will not flow through an electrical insulator . By historical convention,
18840-416: The electrons. However, depending on the conditions, an electric current can consist of a flow of charged particles in either direction, or even in both directions at once. The positive-to-negative convention is widely used to simplify this situation. The process by which electric current passes through a material is termed electrical conduction , and its nature varies with that of the charged particles and
18997-428: The elementary charge, and any amount of charge an object may carry is a multiple of the elementary charge. An electron has an equal negative charge, i.e. −1.602 176 634 × 10 coulombs . Charge is possessed not just by matter , but also by antimatter , each antiparticle bearing an equal and opposite charge to its corresponding particle. The presence of charge gives rise to an electrostatic force: charges exert
19154-512: The existing John Wayne Airport . But subsequent voter initiatives and court actions caused the airport plan to be permanently shelved. It has developed into the Orange County Great Park and housing. In the 21st century, the social landscape of Orange County has continued to change. The opioid epidemic saw a rise in Orange County, with unintentional overdoses becoming the third highest contributor of deaths by 2014. As in other areas,
19311-495: The form of a sine wave . Alternating current thus pulses back and forth within a conductor without the charge moving any net distance over time. The time-averaged value of an alternating current is zero, but it delivers energy in first one direction, and then the reverse. Alternating current is affected by electrical properties that are not observed under steady state direct current, such as inductance and capacitance . These properties however can become important when circuitry
19468-450: The housing of braceros in their city, forcing the nearby town of Placentia to board them within the segregated Mexican colonia ." The small town had grown significantly by the 1960s, with more than 1,000 residents by the 1960 Census . Three annexation attempts were made by adjoining cities: Brea in 1958 and Anaheim and Placentia in 1963. These experiences culminated in incorporation, which occurred in 1967. The new city implemented
19625-763: The inception of Savi Ranch, the Home Depot was located in Savi Ranch East. In the early 2000s, however, the Super Kmart location in Savi Ranch West ceased operations and The Home Depot moved into the location it previously occupied, taking the sales tax revenue with it to Anaheim. Also located in the Yorba Linda side of Savi Ranch is the headquarters of John Force Racing , housing operations & hosting displays of legendary 16-time NHRA Funny Car Champion John Force , his team of drivers, and their cars. An on-site museum
19782-481: The industrial orange groves. Poor working conditions resulted in the Citrus Strike of 1936 , in which more than half of the orange industry's workforce, largely Mexican, demanded better working conditions. The strike was heavily repressed, with forced evictions and state-sanctioned violence being used as tactics of suppression. Carey McWilliams referred to the suppression as "the toughest violation of civil rights in
19939-411: The late 1970s, Vietnamese and Latino immigrants began to populate central Orange County. In the 1980s, Orange County had become the second most populous county in California as the population topped two million for the first time. In the 1990s, red foxes became common in Orange County as a non-native mesopredator , with increasing urban development pushing out coyote and mountain lion populations to
20096-440: The late 19th century, with Downtown Santa Ana being the home of the county, state and federal institutions. However, far more commercial activity is concentrated in clusters of newer commercial development located further south in the county's edge cities . The three largest edge cities, from north to south, are: A contiguous strip of commercial development (an edge city ) stretches from Disneyland through to MainPlace Mall along
20253-400: The material through which they are travelling. Examples of electric currents include metallic conduction, where electrons flow through a conductor such as metal, and electrolysis , where ions (charged atoms ) flow through liquids, or through plasmas such as electrical sparks. While the particles themselves can move quite slowly, sometimes with an average drift velocity only fractions of
20410-601: The middle of the county from northeast to southwest. Its major tributary to the south and east is Santiago Creek . Other watercourses within the county include Aliso Creek , San Juan Creek , and Horsethief Creek. In the North, the San Gabriel River also briefly crosses into Orange County and exits into the Pacific on the Los Angeles-Orange County line between the cities of Long Beach and Seal Beach . Laguna Beach
20567-544: The nation." The Los Angeles flood of 1938 devastated some areas of Orange County, with most of the effects being in Santa Ana and Anaheim, which were flooded with six feet of water. As an eight-foot-high rush of water further spilled out of the Santa Ana Canyon , forty-three people were killed in the predominately Mexican communities of Atwood and La Jolla in Placentia . The devastation from this event, as well as from
20724-441: The overall average for the year at 63 °F (17 °C). Humidity , likewise respectively, is 52%, 60%, and 56% on average. Yorba Linda is in a Mediterranean climate ( Csa ). The 2010 United States Census reported that Yorba Linda had a population of 65,237. The population density was 3,208.8 inhabitants per square mile (1,238.9/km). The racial makeup of Yorba Linda was: The Census reported that 64,044 people (99.7% of
20881-646: The population) lived in households, 97 (0.2%) lived in non-institutionalized group quarters, and 93 (0.1%) were institutionalized. There were 21,576 households, out of which 8,535 (39.6%) had children under the age of 18 living in them, 15,102 (70.0%) were opposite-sex married couples living together, 1,844 (8.5%) had a female householder with no husband present, 758 (3.5%) had a male householder with no wife present. There were 554 (2.6%) unmarried opposite-sex partnerships , and 101 (0.5%) same-sex married couples or partnerships . 3,119 households (14.5%) were made up of individuals, and 1,515 (7.0%) had someone living alone who

There were 19,252 households, out of which 44.8% had children under the age of 18 living with them, 72.3% were married couples living together, 8.3% had a female householder with no husband present, and 16.4% were non-families. 12.4% of all households were made up of individuals, and 4.7% had someone living alone who was 65 years of age or older. The average household size was 3.05 and
21195-428: The principle, now known as Faraday's law of induction , that the potential difference induced in a closed circuit is proportional to the rate of change of magnetic flux through the loop. Exploitation of this discovery enabled him to invent the first electrical generator in 1831, in which he converted the mechanical energy of a rotating copper disc to electrical energy. Faraday's disc was inefficient and of no use as
21352-483: The process of repeated, labored import. The first grape crop production was produced in 1782 at San Juan Capistrano , with vines potentially brought through supply ships in 1778. Viticulture became an increasingly important crop in Los Angeles and Orange Counties through the subsequent decades. By the 1850s, the regions supported more than 100 vineyards . In 1857, Anaheim was founded by 50 German-Americans (with lineage extending back to Franconia ) in search of
21509-437: The property to repair the damage, and tours are now available one day per month. A section of the land was sold in 1907 by the Yorba family to Fullerton businessman Jacob Stern, who used the land for barley fields and sheep grazing. Stern subsequently sold the tract to the Janss Investment Company , which first called the area Yorba Linda, and proceeded to subdivide the land and sell it for agriculture and manufacturing. In 1910,
21666-551: The residence were killed. In October of the heightened 2020 California wildfires , fires destroyed 1 home and damaged 10 others in the Yorba Linda area. Initially a brush fire, the Blue Ridge Fire quickly spread to 13,964 acres before being doused on November 11, 2020. According to the United States Census Bureau , the city has a total area of 20.0 square miles (52 km). 19.5 square miles (51 km) of which
21823-833: The same area. Eleven-digit dialing is therefore now required for local calls. It is bordered by Anaheim on the south, Placentia on the west and southwest, Brea on the northwest, Chino Hills State Park on the north, and Corona on the east. The two nearest seismic faults are the Whittier Fault and the Chino Fault , both of which are part of the Elsinore Fault Zone . The city receives 14 inches (360 mm) to 15 inches (380 mm) of rain per year on average. The average temperatures in January and July are 55 °F (13 °C) and 71 °F (22 °C), respectively, with
21980-549: The second oldest private cemetery in the county, the historic Yorba Cemetery . The land was given to the Roman Catholic Archdiocese of Los Angeles by Bernardo Yorba in 1858 since Orange County was not established out of Los Angeles County as a separate county until 1889. The cemetery closed in 1939 and was subsequently vandalized; however, in the 1960s, the Orange County Board of Supervisors took possession of
22137-686: The southern tip of the city and SR 91 runs through the eastern tip of the city. A Metrolink commuter rail station was rejected by its city council in 2004. The primary commercial district in Yorba Linda is Savi Ranch. Smaller shopping centers in the city include: In 2016, construction began on the Yorba Linda Town Center, a 125,000-square-foot shopping and dining center on the corner of Yorba Linda Boulevard and Imperial Highway, featuring Bristol Farms as an anchor tenant. The shopping center opened in April 2019. There are over 1,000 businesses in
22294-454: The special property that it is conservative , which means that the path taken by the test charge is irrelevant: all paths between two specified points expend the same energy, and thus a unique value for potential difference may be stated. The volt is so strongly identified as the unit of choice for measurement and description of electric potential difference that the term voltage sees greater everyday usage. For practical purposes, defining
