Science definitions for capacitance

capacitance

[ kə-păs′ĭ-təns ]

A measure of the ability of a configuration of materials to store electric charge. In a capacitor, capacitance depends on the size of the plates, the type of insulator, and the amount of space between the plates. Most electrical components display capacitance to some degree; even the spaces between components of a circuit have a natural capacitance. Capacitance is measured in farads. Compare inductance.
