At low frequencies, the emitter- bypass capacitor
A)increases the output voltage.
B)is no longer an ac short.
C)increases the voltage gain.
D)has minimum XC.

Question

Quizplus · Accepted Answer

At low frequencies, the emitter-bypass capacitor acts less like an AC short because its reactance (XC) increases with decreasing frequency, leading to less bypassing of the AC signal through the emitter resistor and thus affecting the circuit's performance.
