Capacitor vs. Varistor

Capacitornoun

(electronics) An electronic component capable of storing electrical energy in an electric field; especially one consisting of two conductors separated by a dielectric.

Varistornoun

(electronics) An electronic component having a variable resistance; used to protect circuits against power surges.

Capacitornoun

a device used in electronic circuits to hold electrical charge, consisting of two conducting plates separated by a nonconducting (dielectric) medium; it is characterized by its capacitance.

Varistor

A varistor is an electronic component with an electrical resistance that varies with the applied voltage. Also known as a voltage-dependent resistor (VDR), it has a nonlinear, non-ohmic current–voltage characteristic that is similar to that of a diode.

Capacitornoun

an electrical device characterized by its capacity to store an electric charge

Capacitornoun

a device used to store an electric charge, consisting of one or more pairs of conductors separated by an insulator.

Capacitor

A capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals.
