A capacitor or condenser is a passive electronic component
consisting of a pair of conductors separated by a dielectric
(insulator). When a potential difference (voltage) exists across the
conductors, an electric field is present in the dielectric. This field
stores energy and produces a mechanical force between the
conductors. The effect is greatest when there is a narrow
separation between large areas of conductor, hence capacitor
conductors are often called plates.
