Initially capacitor is uncharged at t = ...

Initially capacitor is uncharged at `t = 0` switch is closed. Charge on capacitor when current in the circuit is `10 %` of maximum current :

A

`4 muC`

B

`8 muC`

C

`36 muC`

D

`16muC`

Text Solution

Verified by Experts

The correct Answer is:
C
Maximum current in the circuit is
`(20)/(10) = 2A`
when current is 0.2 A

Apply KVL-
`-(q)/(2)-0.2xx10+20=0rArr q=36muC`
