Choke coil is used to control

A

`AC`

B

`DC`

C

Both `AC` and `DC`

D

Neither `AC` nor `DC`

Text Solution

Verified by Experts

The correct Answer is:
A
The choke coil can be used only in AC circuits, not in DC circuits, because for DC `(omega=0)` the inductive reactance `X_(L)=omegaL`. Of coil is zero, only the resistance the coil remains effective which too is almost zero.
