Discharging a capacitor |
- If the capacitor is isolated, the presence of the dielectric decreases the potential difference between the plates.
- If the capacitor is connected to a battery, the presence of the dielectric increases the charge stored in the capacitor.
- The introduction of the dielectric increases the capacitance of the capacitor
