Electrode vs. Cathode: What's the Difference?

Electrode and Cathode Definitions

Electrode

A solid electric conductor through which an electric current enters or leaves an electrolytic cell or other medium.

Cathode

A negatively charged electrode, as of an electrolytic cell, storage battery, diode, or electron tube.

Electrode

A collector or emitter of electric charge or of electric-charge carriers, as in a semiconducting device.

Cathode

The positively charged terminal of a primary cell or a storage battery that is supplying current.

Electrode

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

Cathode

(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.

Electrode

A collector or emitter of electric charge in a semiconducting device.

Cathode

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

Electrode

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.

Cathode

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

Electrode

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

Cathode

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

Cathode

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.

Cathode

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

Cathode

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