If there is any ac voltage at an amplifier's bypass emitter,it means that the
A) transistor is shorted.
B) transistor is open.
C) coupling capacitor is open.
D) bypass capacitor is open.

Quizplus · Accepted Answer

If there is any AC voltage at an amplifier's bypass emitter, it means that the bypass capacitor is open. The bypass capacitor is responsible for providing a low impedance path for the AC signal to ground and if it is open, the AC signal will not be bypassed and will appear at the emitter. Therefore, the best choice is D - bypass capacitor is open.
