A capacitor `C=100 muF` is connected to three resistor each of resistance `1 kOmega` and a battery of `emf 9V`.

The switch `S` has been closed for long time so as to charge the capacitor. When switch `S` is opened, the capacitor discharges with time constant

A

`33 ms`

B

`5 ms`

C

`3.3 ms`

D

`50 ms`

Text Solution

Verified by Experts

The correct Answer is:
D

`tau = RC = 500 Omega xx 100 xx 10^(-6)F`
`= 5 xx 10^(-2) sec. = 50 ms`
