A capacitor is connected to a battery and given time to reach its full charge. You then slide a sheet of plastic between the plates of the capacitor, while holding the potential difference across the capacitor constant by leaving the battery connected. Which of the following has increased as a result of this change? I. The capacitance of the capacitor. II. The potential difference across the capacitor. III. The charge on the plates of the capacitor. IV. The energy stored by the capacitor.
