### Question

A parallel plate capacitor is charged to a potential. difference of 50V. It is discharged through a resistance. After 1 second, the potential difference between plates becomes 40V. Then

### Choices

Choice (4) Response

a.

Potential difference between the plates after 2 seconds will be 20 V

b.

Fraction of stored energy after 1 second is 16/25

c.

Potential difference between the plates after 2 seconds will be 30V

d.

Fraction of stored energy after 1 second is 4/5

## Passage

Capacitor C 3 in the circuit is variable capacitor (its capacitance can be varied). Graph is plotted between potential differences V, (across capacitor C 1) versus C 3, Electric potential V 1 approaches on asymptote of 10 volts as C 3 → ∞
