Kirchoff's current law describes transistor currents as follows:
A) emitter current equals the sum of collector and base currents.
B) collector current equals the sum of base and emitter currents.
C) base current equals the sum of collector and emitter currents.
D) emitter current equals collector current minus the base current.

Question

Quizplus · Accepted Answer

Kirchoff's current law states that the total current entering a node equals the total current leaving the node. In a transistor, the emitter current is the total current leaving the node, and it is equal to the sum of the collector and base currents, which are the currents entering the node. Therefore, choice A is correct. The other choices do not satisfy Kirchoff's current law.
