Resistor of fixed value made by
combining carbon granules
The negative terminal electrode of a
device. The "N" material in a junction diode.
(CRT) Vacuum tube used to display data in a
visual form. Picture tube of a television or computer
terminal.
Unit used to convert chemical energy
into a DC electrical voltage.
Quantity of electrical energy.
Current that flows to charge a capacitor or
battery when voltage is applied.
Chassis
A box of metal or frame into which components are
mounted
Choke
Inductor used to block the flow of
alternating current.
Circuit
Interconnection of components to give an
electrical path between two or more components so that
transfer of current could take place.
Class A amplifier
A linear amplifier biased so the active
equipment conducts through 360 degrees of the i/p waveform.
Class B amplifier
An amplifier with two active equipments. The
active components are biased so that each conducts for
about 180 degrees of the i/p waveform cycle.
Class C amplifier
An amplifier in which the active euipment
conducts for less than 180 degrees of the i/p waveform
cycle.
Clipper
A diode circuit used to throw some part of a
waveform
Clipping
Distortion caused by overdriving an
amplifier.
Clock
A square waveform used for synchroniziation and
timing of several circuits.
Closed circuit
Circuit having a full path for current
flow.
Coaxial cable
Transmission line in which the signal
carrying conductor is coated by a dielectric & another
conductor.
Collector
The semiconductor region in a bipolar
junction transistor through which a flow of charge carriers
leaves the base region. The other two are Base and emitter.
Coulomb
Unit of electric charge. A negative coulomb
charge consists of 6.24 × 1018
electrons.
Coupling
Combining two or more circuits.
CRT
Abbreviation for cathode ray tube.
Current
Measured in amperes, it is the flow of
electrons through a conductor. Also called as electron flow.
Current amplifier
Amplifier to increase signal current.
Current divider
Parallel network designed to divide the
total current of a circuit
