The ac base-emitter voltage divided by the ac emitter current equals
A) ac resistance.
B) dc resistance.
C) reactance.
D) impedance.

Question

Quizplus · Accepted Answer

The ac base-emitter voltage divided by the ac emitter current gives the ac resistance of the transistor. This is because the ratio of the voltage to current gives the resistance, which is the opposition to the flow of current in the transistor. The ac resistance represents the dynamic resistance of the transistor and is important in small-signal analysis.
