The ac equivalent circuit of a FET amplifier assumes that the capacitors A)have an X_C of 600 ▲ at the signal frequency. B)are treated like opens. C)have an X_Cof 1 M▲ at the signal frequency. D)are treated like shorts.

Question

Quizplus · Accepted Answer

In the AC equivalent circuit of a FET amplifier, capacitors are treated like shorts because at signal frequency, they offer very low impedance, allowing AC signals to pass through them as if they were not present. This simplifies the analysis of the circuit's behavior with AC signals.
