A circuit consists of a 12 V battery, a 4 Ω resistor, and a capacitor with capaci	ance $C$. The circuit is connected to a switch that is initially open. At $t = 0$, the switch is closed. Find the charge $Q(t)$ on the capacitor at time $t$.

Accepted Answer

Q(t) = C \cdot 12 \left$ 1 - e^{-\frac{t}{RC}} \right $
