Three capacitors (of capacitances C, 2C ...

Three capacitors (of capacitances `C`, `2C` and `3C`) and three resistors (of resistance `R`, `2R` and `3R`) are connected with a battery and switch `S` as shown in the figure. When switch `S` is open, charges on the capacitors are shown. Switch `S` is closed at `t=0 sec`. The time constant of the circuit will be

A

`RC`

B

`(6RC)/(11)`

C

`(36RC)/(121)`

D

None

Text Solution

Verified by Experts

The time constant is independent of charge on the capacitor or voltage source
