Starting electronics
circuit diagram method of illustrating a circuit using symbols,
so that all electrical connections are shown but not
physical ones.
closed-loop gain the gain of an operational amplifier with
feedback.
collector current shortened form for collector-to-emitter
current of a transistor.
conventional current current which is assumed to flow from
a positive potential to a more negative potential. Conventional
current is, in fact, made up of a flow of electrons (which are
negative) from a negative to more positive potential.
corner frequency the frequency at which a signal size
changes from one slope to another, when viewed as a graph
of size against frequency. In the simple filter circuits in this
article, the corner frequency, f, is given by the expression:
c o u l o m b standard unit to measure quantity of
electricity.
current flow rate of electricity. Current is measured in
amps.
current gain h fe
, shortened forms for forward current transfer
ratio, common emitter, which is the ratio:
of a transistor.
