  • noun an assembly of one or more pairs of conductors separated by insulators, able to store an electric charge where there is a voltage difference


  • noun an electronic component that can store charge


  • A device used to introduce capacitance into an electric circuit. The device consists of conducting plates insulated from each other by a layer of dielectric material.


  • A component which has capacitance. The conductors separated by the dielectric material are known as electrodes or plates. The value of the capacitance will vary depending on the size, shape, and composition of the conductors, the distance between them, and on the dielectric. In addition to storing charge, a capacitor blocks DC, and may be fixed or variable. There are various types, including mica, electrolytic, metallized paper, and MOS capacitors. Formerly known as condenser (3).
