A capacitor acts as an infinite resistance for

A

DC circuits.

B

AC circuits.

C

DC as well as AC circuits.

D

neither AC nor DC circuits.

Text Solution

Verified by Experts

The correct Answer is:
A

(A) : After charging gets completed then no current flows through the branch of capacitor in the DC circuit . Hence we can say that it behaves s infinite resistance in DC circuits . Option (A) is correct.
