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.
Electric Island: Season Finale
Electric Island: Season Finale is the closing edition of Electric Island, a Toronto house-and-techno day-festival series founded in 2013, ending the season on the Labour Day long weekend.
Electric kettle
An electric kettle is a countertop appliance that heats water through a resistive element and switches off at boiling, common in nearly every household in tea-drinking countries like the United Kingdom.
Electric knife
An electric knife is a kitchen tool with motor-driven reciprocating blades, usually two parallel serrated blades, used for carving meat, slicing bread, and cutting foam.
Electric Lady Studios
Electric Lady Studios is a recording studio in Greenwich Village, New York City, built for Jimi Hendrix, who opened it in 1970 shortly before his death.
Electric Ladyland
Electric Ladyland is the third and final studio album by the Jimi Hendrix Experience, a double album released in October 1968 that reached number 1 in the US.
Electric light
Electric light, also called electric lighting, is illumination made by converting electricity into visible light, from Edison's 1879 incandescent bulb to arc, fluorescent, and LED lamps.
Electric Light Orchestra
Electric Light Orchestra (ELO), English rock band formed in Birmingham in 1970 by Jeff Lynne, Roy Wood, and Bev Bevan; fuses classical orchestration with Beatlesque pop; split 1986, revived 2014, Rock Hall 2017.
Electric Light Orchestra discography
The Electric Light Orchestra (ELO) discography spans 14 studio albums from 1971's debut to 2019's From Out of Nowhere, plus the Xanadu soundtrack, live albums, and compilations.
Electric locomotive
An electric locomotive is a railway locomotive with electric motors that draws power from overhead wires or conductor rails, offering high power and fast acceleration.
Electric machine
An electric machine, also called electrical machinery, is an electromechanical device that converts energy between electrical and mechanical forms using magnetic fields, including motors, generators, and transformers.
Electric motor
An electric motor is a machine that converts electrical energy into mechanical energy using a magnetic field and current, ranging from appliances to industrial machines.
Electric motorcycles and scooters
Electric motorcycles and scooters are two-wheeled road vehicles driven by an electric motor and rechargeable battery, ranging from 14 kg rental e-scooters to highway-capable motorcycles.
Electric Mud
Electric Mud: 1968 Muddy Waters psychedelic blues album on Chess' Cadet Concept (LPS 314), recorded May 1968 at Ter Mar Studios with Rotary Connection players; big seller, Rolling Stone panned it, later reassessed as a classic.
Electric multiple unit
An electric multiple unit (EMU) is a self-propelled passenger train with motors distributed among its carriages rather than concentrated in a locomotive, common in commuter and high-speed service.
Electric potential
Electric potential, also called electrostatic potential, is the potential energy per unit charge at a point in space, measured in volts and defined as V = U/q.
Electric potential energy
Electric potential energy, also called electrostatic energy, is the energy a system of charges has by virtue of their positions in an electric field; a free charge converts it into kinetic energy.
Electric power
Electric power is the rate at which electric energy is transferred, measured in watts or megawatts, and produced from sources like coal, gas, and wind.
Electric Power Development (J-POWER)
Electric Power Development Co., Ltd. (電源開発株式会社), known commercially as J-POWER, is a Japanese power generation company founded in 1952, headquartered in Tokyo, and fully privatized in 2004.
Electric power distribution
Electric power distribution is the final stage of the electricity supply chain, delivering power from distribution substations to customers at voltages from 4 kV down to 120 V.
Electric Power Research Institute
The Electric Power Research Institute is an independent nonprofit that conducts energy and environmental research for the electricity sector, founded in 1972 and headquartered in Palo Alto, California.
