In a well-designed coupling circuit,the coupling capacitor approximates
A) an ac open.
B) a dc short.
C) a dc open.
D) an ac short.

Question

Quizplus · Accepted Answer

In a well-designed coupling circuit, the coupling capacitor should allow the AC signal to pass through while blocking any DC voltage. Therefore, the capacitor should act like an AC short circuit while behaving like a DC open circuit. Hence, the best choice is D- an AC short.
