Diode vs. Capacitor

Diodenoun

(electronics) An electronic device that allows current to flow in one direction only; used chiefly as a rectifier.

Diodenoun

a thermionic tube having two electrodes; used as a rectifier

Diodenoun

a semiconductor that consists of a p-n junction

Diode

A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a plate, in which electrons can flow in only one direction, from cathode to plate.

Capacitornoun

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

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.

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.
