In the circuit shown in figure, the battery is an ideal
\( \mathrm{P} \) one, with emf \( \mathrm{V} \). The capacitor is initially uncharged. The switch \( \mathrm{S} \) is closed at time \( t=0 \).
W
(a) Find the charge \( \mathrm{Q} \) on the capacitor at time t.
(b) Find the current in \( \mathrm{AB} \) at time t. What is its limiting value as \( \mathrm{t} \rightarrow \infty \) ?
