(5C20.10) Parallel Plate Capacitor with a Dielectric
The parallel plate capacitor is charged by the power supply and the plates are separated, increasing the voltage between the plates. A thick dielectric sheet is inserted between the capacitor plates, decreasing the voltage. Because the charge on the plates remained constant, it means that the insertion of the dielectric increased the capacitance. This allows more charge to be stored by the capacitor at the same voltage.
