At steady state current does not pass through capacitor Brach. Re q of the circuit =(6 × 3/6+3)+3=5 Ω i=15 / 5=3 Amp.

Applying kirchoff at steady state in loop ABCDA 1 × 3+q / C-15=0 q / C=12 p.d. across capacitor =12 volt

Q. In the circuit shown, the cell is ideal, with emf $= 15 V$ . Each resistance is of $3 Ω$ . The potential difference (in $V$ ) across the capacitor is -

At steady state current does not pass through capacitor Brach.
$R_{e q}$ of the circuit $= \frac{6 \times 3}{6 + 3} + 3 = 5 Ω$
$i = 15/5 = 3 A m p$ .

Applying kirchoff at steady state in loop
$A BC D A$
$1 \times 3 + q / C - 15 = 0$
$q / C = 12$
p.d. across capacitor $= 12$ volt
