Transistor operation is being discussed. Technician A says that when the base of a PNP is connected to ground, the transistor is turned off. Technician B says that when the base of an NPN transistor has a positive voltage applied to it, the transistor is turned on. Who is correct?
A)A only
B)B only
C)both A and B
D)neither A nor B

Question

Quizplus · Accepted Answer

Technician B is correct because an NPN transistor turns on when a positive voltage is applied to its base. Technician A is incorrect because a PNP transistor turns on when the base is connected to ground or a lower voltage than the emitter.
