Ac amplifier voltage gain decreases at low frequencies because
A) coupling and bypass capacitive reactances increase.
B) coupling and bypass capacitive reactances decrease.
C) coupling and bypass capacitors act like short circuits.
D) direct coupling is used.

Question

Quizplus · Accepted Answer

At low frequencies, the coupling and bypass capacitive reactances increase, which means that they offer less resistance to the AC signal and allow more of it to pass through. This results in a decrease in AC voltage gain.
