Figure shows a battery with emf 15 V in a circuit with `R_1 = 30Omega, R_2 = 10 Omega, R_3 = 20 Omega` and capacitance `C = 10 muF`. The switch S is initially in the open position and is then closed at time t= 0. What will be the fimal steady - state charge on capacitor?

A

`75 muC`

B

`50 muC`

C

`10 muC`

D

none of these

Verified by Experts

The correct Answer is:
A
a. `i = 15/60 = 1/4 A`
`V_(AB) = 1/4 xx 30 = 7.5 V`
`q = eV = 10 xx 7.5 = 75 muC`.
