Electrical Definitions

Emitter Coupled Logic : A group of integrated logic circuits coupled by their emitters.

Emitter Follower : A transistor amplifier using common collector mode of operation.The output is derived from emitter.

Encoder : It is a digital circuit which converts the information/data into coded form.

Energy Levels : The possible values of energy of an atom or molecule. Quantum theory dictates that only certain fixed values are possible and these may only change by an integral multiple of some fixed amount.

Extended Interaction : Interaction between an electron beam or stream and nearly synchronous travelling radio frequency signal over a physical distance comparatable to a wave length.

E.M.F. : The force which sets up a flow of current in a circuit is called e.m.f. or 'Electro Motive Force'.

Electrolyte : The chemical solution which undergoes chemical changes on amount of conduction of current is called an electrolyte.

Electrolytic Capacitor : An electrolytic capacitor consists of an electrolyte between the two sets of plates.The electrolyte forms an insulation layer on positive plates when the capacitor is connected across a DC source,the insulation so formed acts as dielectric.

Electronic Counter : An electronic equipment based on logic units which is meant for counting RPM etc. is called an electronic counter.
