|
Electric Field: A field of force that exists between positively and negatively charged surfaces. In a capacitor, the field is assumed to consist of lines of force which extend through the dielectric from the positive to the negative plate.
|
|
Electrode: An element of an electron tube or semiconductor device that takes part in conduction, such as the plate, anode, cathode and filament.
|
|
Electron Emmission- The escape of electrons from certain materials.
|
|
Electron tube:An arrangement of two or more conductive elements, enclosed in an envelope, to control electron flow in a circuit.
|
|
Element: Any of the electrical parts of an electron tube such as the filament, cathode or plate.
|
|
Eddy Current:Circulating current produced in connecting materials by a varying magnetic field. Eddy currents are undesirable in the core of a transformer.
|
|
Efficiency: Usually given as a percentage, efficiency is the ratio of the output to the input. The efficiency changes with power output levels of any inverter.
|
|
Electrolyte: The fluid in batteries (sulfuric acid and distilled water) that serves as the transport medium for positively and negatively charged ions.
|
|
Equalization: A controlled overcharge that restores all cells in a battery to 100% state of charge (SOC).
|
|
Equalizing Charge: A charge at a voltage higher that that which is normally used in battery charging; the purpose of which is to bring all the battery cells up to the same specific gravity of full charge.
