Diode vs. Resistor

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.

Resistornoun

One who resists, especially a person who fights against an occupying army.

Resistornoun

An electric component that transmits current in direct proportion to the voltage across it.

Resistornoun

an electrical device that resists the flow of electrical current

Resistor

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
