When a capacitor charges, electrons flow onto one plate and move off the other plate. This process will be continued until the potential difference across the capacitor is equal to the potential difference across the battery. Because the current changes throughout charging, the rate of flow of charge will not be linear. At.

A capacitor is an essential component found in various electrical devices such as computers, radios, and other similar equipment.
