In figure (a), an uncharged capacitor has been illustrated, because the same number of free electrons exists on plates A and B. When a switch is closed, as has been shown in figure (b), then the source, moves electrons towards B via the circuit. In this way, the flow of electrons starts from plate A, and electrons start to store on plate B.

Discharging a Capacitor A circuit with a charged capacitor has an electric fringe field inside the wire. This field creates an electron current. The electron current will move opposite the direction of the electric field. However, so long as the electron current is running, the capacitor is being discharged.
When connected to a battery, the capacitor stores electrostatic energy. This energy is in the form of charge on its plates which raises the potential difference between the plates. When required, this capacitor can release this stored energy and gets discharged. A capacitor is charged by connecting it to a voltage source and a resistor.
