WhatsAppI just found in an alley next to a music store an Erie .047 uf capacitor. It''s one of the old style plastic case big capacitors. It sounds better than the ceramic one that used to be in there. I like film stlye capacitors for tone controls rather than the ceramic. BTW, a capacitor is always in the circuit unless a "no-load" stlye tone control ...
WhatsAppA capacitor is a device that stores energy. Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this constitutes an open circuit, DC current will not flow through a capacitor. If this simple device is connected to a DC voltage source, as ...

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…
