In this article, you will learn about charging and discharging a capacitor. When a voltage is applied on a capacitor it puts a charge in the capacitor. This charge gets accumulated between the metal plates of the capacitor. The accumulation of charge results in a buildup of potential difference across the capacitor plates.
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.
The charge remains in the capacitor, with or without the applied voltage connected. The capacitor discharges when a conducting path is provided across the plates, without any applied voltage. Actually, it is necessary only that the capacitor voltage be more than the applied voltage.
Because the current changes throughout charging, the rate of flow of charge will not be linear. At the start, the current will be at its highest but will gradually decrease to zero. The following graphs summarise capacitor charge. The potential difference and charge graphs look the same because they are proportional.
A capacitor can store the amount of charge necessary to provide a potential difference equal to the charging voltage. If 100 V were applied, the capacitor would charge to 100 V. The capacitor charges to the applied voltage because it takes on more charge when the capacitor voltage is less.
Charging and Discharging of Capacitor with Examples- When a capacitor is connected to a DC source, it gets charged. As has been illustrated in figure 6.47. In figure (a), an uncharged capacitor has been illustrated, because the same number of free electrons exists on plates A and B.
