In the circuit shown, the cell is ideal, with e.m.f. = 15 V. Each resistance is of 3 Ω. The potential difference across the capacitor is 

a
Zero
b
9 V
c
12 V
d
15 V

detailed solution

Correct option is C

No current flows through the branch where  capacitor is connectedTotal resistance  2R×R3R+R=5R/3=5Ω P.D acros sthe capacitor=1×R+3R=4R=12V
