A voltage is produced across a capacitor when its charges are separated. The capacitor stores electrical energy in its electric field. The amount of stored energy is directly proportional to the applied voltage and the capacitance of the capacitor, which is a measure of its ability to store charge.

An electric field forms across the capacitor. Over time, the positive plate (plate I) accumulates a positive charge from the battery, and the negative plate (plate II) accumulates a negative charge. Eventually, the capacitor holds the maximum charge it can, based on its capacitance and the applied voltage.
The capacitor's ability to hold a charge for a long time is made possible by the insulation between the plates. Capacitance, voltage capacity and operating temperature range are only a few of the features of a capacitor that are affected by the dielectric.

A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.
