If the switch is closed for long time and then open at `t = 0`, the P.D across indicator at `t = 0` is

A

`OV`

B

`50V`

C

`20V`

D

`100V`

Text Solution

Verified by Experts

The correct Answer is:
D

at steads state `5A` current through inductor hence P.D across indicator at `t=0" " 20xx5 = 100V`
