ca•pac•i•tor
(kəˈpæs ɪ tər)n.
a device for accumulating and holding a charge of electricity, consisting of two equally charged conducting surfaces having opposite signs and separated by a dielectric. Also called condenser.

A capacitor is charged when electrons from a power source, such as a battery, flow to one of the two plates. Because the electrons cannot pass through the insulating layer, they build up on the first plate, giving it a negative charge. Electrons on the other plate are attracted to the positive terminal of the battery, causing that plate to become positively charged.
ca·pac·i·tor
(kə-păs′ĭ-tər) A device used to store electric charge. Capacitors consist of two charged metal plates separated by an electrical insulator. The charge is supplied by connecting the plates to a source of electricity. The positive charge is stored on one of the plates, and the negative charge is stored on the other. Capacitors are used to regulate the flow of charge in electric circuits. ♦ The ability of a capacitor to store charge is called its capacitance (kə-păs′ĭ-təns). The capacitance depends on the size of the plates, the type of insulator, and the amount of space between the plates.
