(a)[2]
Suggest why, when the capacitor is connected across the terminals of a battery, the capacitor stores energy, not charge.
(b)[2]
Define the capacitance of the capacitor.
(c)[2]
The capacitor is charged so that the potential difference across its plates is $V_0$. It is then connected across a resistor for a short time. It is then disconnected. The energy stored in the capacitor is reduced to $\frac{1}{16}$ of its initial value. Determine, in terms of $V_0$, the potential difference across the capacitor.
