In the circuit shown in figure, the capacitor is charged with a cell of `5V`.If the switch is closed at `t=0`, then at `t=12s`, charge on the capacitor is

A

`(0.37)10muC`

B

`(0.37)^(2)10muC`

C

`(0.63)10muC`

D

`(0.63)^(2)10muC`

Text Solution

Verified by Experts

The correct Answer is:
B
`tau_c=CR=6s`
`q_0=CV=10muC`
`Now, q=q_0e^(-t/tauC)=(10muC)e^(-12/6)`
`=(1/6)^2(10muC)`
`=(0.37)^2(10muC)`
