Electrode vs. Cathode

Electrodenoun

the terminal through which electric current passes between metallic and nonmetallic parts of an electric circuit

Electrodenoun

a collector or emitter of electric charge in a semiconducting device

Electrodenoun

a conducting object by which electricity is conveyed into or from a solution or other non-metallic conducting medium; esp., the ends of the wires or conductors, leading from source of electricity, and terminating in the medium traversed by the current.

Electrodenoun

a conductor used to make electrical contact with some part of a circuit

Electrode

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air).

Cathodenoun

(electricity) An electrode, of a cell or other electrically polarized device, through which a positive current of electricity flows outwards (and thus, electrons flow inwards). It usually, but not always, has a positive voltage.

Cathodenoun

The electrode at which chemical reduction of cations takes place, usually resulting in the deposition of metal onto the electrode.

Cathodenoun

(electronics) The electrode from which electrons are emitted into a vacuum tube or gas-filled tube.

Cathodenoun

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

Cathodenoun

The part of a voltaic battery by which the electric current leaves substances through which it passes, or the surface at which the electric current passes out of the electrolyte; the negative pole; - opposed to anode.

Cathodenoun

a negatively charged electrode that is the source of electrons in an electrical device

Cathodenoun

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

Cathode

A cathode is the electrode from which a conventional current leaves a polarized electrical device. This definition can be recalled by using the mnemonic CCD for Cathode Current Departs.
