Electric Welding

A term often used for arc welding.

Electric-drive Cooling Fan

1. An engine-cooling fan driven by an electric motor. 2. An electrically controlled fan that cycles ON and OFF with the air conditioner control, if predetermined system and/or ambient temperatures are exceeded.

Electricity

Electricity is the movement of free electrons from one atom to another through a conductor.

Electrochemical

The chemical action of two dissimilar materials in the presents of a carossive acid.

Electrochromic Mirror

A mirror that automatically adjusts the amount of reflectance based on the intensity of glare.

Electrocution

Death caused by electrical current through the heart, usually in excess of 50 ma.

Electrode

1. A component of the electrical circuit that terminates at a gap across which current must arc. 2. The contacts of a semiconductor material that emits, collects or controls the movement of electrons or holes. 3 A rod used in welding.

Electrohydraulic Pressure Actuator

A valve that will provide a continuous adjustment of fuel pressure in certain fuel-injection systems.

Electrohydraulic Unit

The microprocessor and hydraulic units are combined in one unit.

Electroluminescence

Exciting a phosphor and causing it to glow by using electricity.

Electroluminescent

A product that converts electricity into light when a solid phosphor material is subjected to AC current. Some head units feature an electroluminescent display.

Electrolysis

1. Charging a material's chemical composition by applying an electromotive force and having an electrical current flow through it. 2. The process where an electric current is passed through an electrolytic solution, causing a chemical reaction.

Electrolyte

1. A substance in which the condition of electricity is accompanied by chemical action.2. Any substance which, in solution, is separated into ions and is made capable of conducting electric current. 3. The sulfuric acid solution of a lead-acid battery. 4. A chemical compound that conducts ions from one electrode the the other inside a fuel cell.

Electrolyte

Any liquid that conducts electricity. For instance, the mixture of sulphuric acid and distilled water found in some car batteries is an electrolyte.

Electrolytic Cell

A simple battery consisting of the container, two electrodes, and the electrolyte.

Electromagnet

A device consisting of a ferrous-metal core and a coil that produces appreciable magnetic effects when an electric current exists in the coil.

Electromagnetic

Refers to a device which incorporates both electronic and mechanical principles together in its operation.

Electromagnetic Clutch

An electrically controlled device used to start and stop the compressor action.

Electromagnetic Gauges

A type of dash instrument gauge that uses a small electromagnetic coil for gauge needle movement.

Electromagnetic Induction

1. The induction of a voltage into a conductor by passing the conductor through a magnetic field or passing the magnetic field across the conductor. 2. Discovered by Michael Faraday in 1831 Faraday's first rule of electromagnetic induction states that whenever a conductor passes through a magnetic field a voltage is induced into that conductor that is directly proportional to the strength of the magnetic field and the speed of it's movement.
