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…

Are car audio capacitors good or bad, and what''s the deal with …

Since capacitors have to charge, discharge and then charge again, they will supply uneven voltage to your amps which is not a good thing. The idea is to supply at least as much constant current as your electrical system needs on average and have extra head room for when you really crank the volume.
