Technician A says when positive voltage is applied to the base of an NPN transistor, the transistor is turned on. Technician B says when an NPN transistor is turned on, current flows through the collector and emitter of the transistor. Who is correct?
A)A only
B)B only
C)both A and B
D)neither A nor B

Question

Quizplus · Accepted Answer

Technician A is correct because applying positive voltage to the base of an NPN transistor allows it to turn on by allowing current to flow from the base to the emitter. Technician B is also correct because when an NPN transistor is turned on, current indeed flows from the collector to the emitter, completing the circuit.
