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 will exert a .
