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…
Knowing that the energy stored in a capacitor is (U_C = Q^2/(2C)), we can now find the energy density (u_E) stored in a vacuum between the plates of a charged parallel-plate capacitor. We just have to divide (U_C) by the volume Ad of space between its plates …
Capacitors as an energy storage device: It takes work (i.e. energy) to charge up a capacitor from zero charge to q(zero potential to V). The figure shows a capacitor at charge q, …
