Inductors acts as a short circuit for_______________?
Correct answer: B. DC
- A. AC
- B. DC
- C. Both A and B
- D. none of these
Explanation
After the transient has died out, an ideal inductor has zero voltage across it because v = L(di/dt) and steady DC current has constant value. It therefore behaves as a short circuit for steady DC, but it opposes AC according to its inductive reactance.
