Anode vs. Diode

Anodenoun

(electricity) An electrode, of a cell or other electrically polarized device, through which a positive current of electricity flows inwards (and thus, electrons flow outwards). It can have either a negative or a positive voltage.

Diodenoun

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

Anodenoun

The electrode at which chemical oxidation of anions takes place, usually resulting in the erosion of metal from the electrode.

Diodenoun

a thermionic tube having two electrodes; used as a rectifier

Anodenoun

(electronics) The electrode which collects electrons emitted by the cathode in a vacuum tube or gas-filled tube.

Diodenoun

a semiconductor that consists of a p-n junction

Anodenoun

(electronics) That electrode of a semiconductor device which is connected to the p-type material 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.

Anodenoun

The positive pole of an electric battery, or more strictly the electrode by which the current enters the electrolyte on its way to the other pole; - opposed to cathode.

Anodenoun

a positively charged electrode by which electrons leave an electrical device

Anodenoun

the negatively charged terminal of a voltaic cell or storage battery that supplies current

Anode

An anode is an electrode through which the conventional current enters into a polarized electrical device. This contrasts with a cathode, an electrode through which conventional current leaves an electrical device.
