Answer: A capacitor is a device that stores electrical energy in an electric field. It has two terminals and is a neutral electrical component.
When linked to its charging circuit, the capacitor’s ability to store electrical energy serves as one of its main functions. It can also be used as a temporary battery because it will release the stored energy when it is removed from the charging circuit.
The ratio of the charge held in either of the capacitor’s conductors to the potential difference between them is known as the capacitance.
The symbol of capacitor is as follows;
The SI unit of capacitor is capacitance.
