Electric Callboy
Electric Callboy, formerly Eskimo Callboy until the 2022 rename, is a German electronicore band formed in 2010 in Castrop-Rauxel, fusing metalcore with EDM. Known for Tekkno (2022), Tanzneid (2026), Hypa Hypa, and RATATATA with Babymetal.
Electric Capital Frontier
Electric Capital Frontier, or Electric Capital Frontier Fund II, is a crypto venture fund from Electric Capital Partners, founded in Palo Alto in 2018 by Avichal Garg and Curtis Spencer.
Electric car
An electric car, also called a battery-electric car, is a passenger automobile driven by electric motors, with over 17 million sold globally in 2024, above 20% of new-car sales.
Electric car use by country
Electric car use by country covers how battery electric and plug-in hybrid cars are adopted in national markets, with Norway, China, and Europe leading in 2025.
Electric Castle Rumania
Electric Castle, also known as the Electric Castle Festival, is an annual music festival held since 2013 at Bánffy Castle in Bonțida, near Cluj-Napoca, Romania.
Electric chair
The electric chair is a U.S. execution device passing lethal current through electrodes on the body, first used on William Kemmler in New York in 1890; now authorized in nine states, rarely used, last in Tennessee in 2020.
Electric charge
Electric charge, also called electrostatic charge, is a physical property of matter that comes in positive and negative forms; like charges repel, unlike charges attract.
Electric City
Electric City is a 2012 animated post-apocalyptic sci-fi web series created by and starring Tom Hanks, produced by Playtone and Reliance Entertainment for Yahoo Screen, Yahoo's first original scripted series.
Electric current
Electric current is the rate at which electric charge flows past a point or through a surface, measured in amperes, where one ampere is one coulomb per second.
Electric Daisy Carnival
Electric Daisy Carnival (EDC) is an electronic dance music festival organized by Insomniac, first held in Los Angeles in 1997 and best known for its annual EDC Las Vegas.
Electric Daisy Carnival in Asia-Pacific
Electric Daisy Carnival in Asia-Pacific covers editions of the American EDM festival brand in Korea and Thailand, including EDC Thailand's January 2025 debut in Phuket, which drew 150,000 attendees.
Electric dipole moment
The electric dipole moment, written p, is a vector measuring the separation of positive and negative charge, defined as p = qd and measured in coulomb-meters or debye.
Electric dipole transition
An electric dipole transition (E1 transition) is the dominant type of radiative transition between quantum states of an atom or molecule, called "allowed" in spectroscopy.
Electric displacement field
The electric displacement field, or electric flux density, is a vector field in electromagnetism defined as D = ε0E + P, so Gauss's law counts only free charges.
Electric double-layer gating
Electric double-layer gating is a technique in which ions in an electrolyte form a nanometer-thin capacitor at a material's surface, inducing carrier densities far beyond conventional dielectrics and tuning phase transitions.
Electric Dreams (2017 TV series)
Philip K. Dick's Electric Dreams (2017) is a ten-episode Channel 4/Amazon sci-fi anthology adapted from Dick short stories, executive produced by Ronald D. Moore, Michael Dinner, Bryan Cranston, and Isa Dick Hackett; cancelled after one season.
Electric Dreams (film)
Electric Dreams is a 1984 Virgin Pictures romantic sci-fi comedy directed by Steve Barron, starring Lenny Von Dohlen, Virginia Madsen, and Bud Cort as the voice of sentient computer Edgar, a love-triangle film later compared to Her.
Electric Dylan controversy
Electric Dylan controversy: dispute over Bob Dylan's July 25, 1965 electric set at the Newport Folk Festival, the disputed booing, the Pete Seeger axe myth, and its aftermath on the 1966 tour.
Electric eel
Electric eel (Electrophorus), a South American freshwater knifefish, not a true eel; three species since 2019. E. voltai generates up to 860 volts, the strongest animal discharge, using three electric organs covering 80% of its body.
Electric energy consumption
Electric energy consumption, also called electricity consumption, is the use of electrical energy by end users, billed in kilowatthours and growing faster than total energy demand.
Electric field
An electric field is a vector field generated by electric charge giving the force per unit charge at each point, proposed by Michael Faraday in the nineteenth century.
Electric field lines
Electric field lines are curves whose tangent at each point gives the electric field's direction, pointing away from positive charges and toward negative ones, a visualization devised by Faraday.
Electric fields in enzyme catalysis
Electric fields in enzyme catalysis are electrostatic fields inside enzyme active sites that stabilize reaction transition states, accelerating catalysis, as confirmed by vibrational Stark effect measurements.
Electric fireplace
An electric fireplace is an appliance that simulates a wood or gas fire with a flame effect and an electric heater, producing no combustion or fumes.
Electric fish
Electric fish: fishes that generate external electric fields via electrocyte-based electric organs, evolved independently about six times. Weakly electric knifefish and elephantfish electrolocate and communicate; electric eels (Electrophorus, up to 860 V) stun prey.
Electric flux
Electric flux is a scalar measure of how much electric field passes through a surface, connecting the field on a closed surface to enclosed charge.
Electric generator
An electric generator is a device that converts a form of energy, usually mechanical motion, into electricity, based on electromagnetic induction discovered by Michael Faraday in 1831.
Electric guitar
An electric guitar is a guitar that converts the vibration of its metal strings into an amplified electrical signal, developed in the 1920s and 1930s to be heard over big bands.
Electric heating
Electric heating is the production of heat from electricity, through resistive elements or heat pumps, used in home furnaces, baseboard heaters, water heaters, and industrial furnaces and boilers.
Electric Hydrogen Co.
Electric Hydrogen Co. (EH2) is an American manufacturer of high-power PEM electrolyzer systems for green hydrogen, founded in 2020, based in Devens, Massachusetts, and valued at $1 billion in 2023.
