Capacitor
OverviewTheory of operationHistoryNon-ideal behaviorCapacitor typesCapacitor markingsApplicationsHazards and safety
A capacitor consists of two conductors separated by a non-conductive region. The non-conductive region can either be a vacuum or an electrical insulator material known as a dielectric. Examples of dielectric media are glass, air, paper, plastic, ceramic, and even a semiconductor depletion region chemically identical to the conductors. From Coulomb''s law a charge on one conductor wil…
