The current in the given circuit is increasing with a rate `a=4 amp//s`. The charge on the capacitor at an instant when the current in the circuit is 2 amp will be:

A

`4 muC`

B

`5 muC`

C

`6 muC`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
Applying loop law
`4-IR-(LdI)/(dt)-q/C=0`
`4-2xx1-1xx4-q/3=0`

`q=-6muC`
