The base current of a transistor is
5.6 milliamperes, and its current gain is 1146. What is the collector current?
When we’re talking of a transistor,
we’re considering a circuit element that functions either as an amplifier or as a
switch. A transistor has three different
terminals. And those terminals are called the
emitter, the base, and the collector.
In this example, we’re told the
base current of the transistor. And then we’re told that this
current is amplified through a gain factor. The collector current, which we can
call 𝐼 sub 𝑐, is equal to the base current multiplied by this gain.
Multiplying these two values
together, after converting the base current into units of amperes, to two
significant figures, we find the result of 6.4 amps. That’s the collector current of
