Question

The capacitor A shown in fig. has a capacitance `C_(1) = 3 mu F`. The dielectric filled in it has a breakdown voltage of `40 V` and it has a resistance of `3 MOmega`. The capacitor `B` has a capacitance of `C_(2) = 2 mu F` and dielectric in it has a resistance of `2 MOmega`. Breakdown voltage for B is `50 V`. The switch is closed at `t = 0`. Will there be breakdown of any capacitor after the switch is closed ? If yes, which will breakdown first and at what time?

Answer 1

Correct Answer - Capacitor B, `6 l n 6` sec
