E
ELEMENT(1) A substance, in chemistry, that cannot be divided into simpler substances by any means ordinarily available [1]. (2) A part of an antenna that can be either an active radiator or a parasitic radiator [10]. |
ELEPHANT TRUNKDucting used for ventilation purposes [4]. |
ELEVATION ANGLEThe angle between the horizontal plane and the line of sight to a target or object [11] [18]. |
EMERGENCY POWERTemporary source of limited electrical power used upon the loss of the normal power source [18]. |
EMF (ELECTROMOTIVE FORCE)The force that causes electricity to flow between two points with different electrical charges or when there is a difference of potential between the two points. The unit of measurement is volts [1]. |
EMITTERThe element in a transistor that emits current carriers (electrons or holes) [7] [13]. |
EMITTER-INJECTION MODULATORThe transistor equivalent of the cathode modulator. The gain is varied by changing the voltage on the emitter [12]. |
ENAMELA synthetic compound of cellulose acetate (wood pulp and magnesium). Used to insulate wire in meters, relays, and motor windings [4]. |
ENCAPSULATEDImbedded in solid material or enclosed in glass or metal [14]. |
END-FEED METHODA method in which one end of an antenna is connected through a capacitor to the final output stage of a transmitter [10]. |
