- the ratio of an impressed charge on a conductor to the corresponding change in potential.
- the ratio of the charge on either conductor of a capacitor to the potential difference between the conductors.
- the property of being able to collect a charge of electricity. Symbol: C
- the property of a system that enables it to store electric charge
- a measure of this, equal to the charge that must be added to such a system to raise its electrical potential by one unit
- 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.
