Capacitors and their Function in Electronic Devices
A typical capacitor is composed of two conductive plates separated by a dielectric material, which is an insulator. When a voltage is applied across the plates, an electric field is created, leading to the accumulation of negative charge on one plate and an equivalent positive charge on the other, thus storing energy in the electric field.
