Cathode vs. Cation

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.

Cationnoun

(physical chemistry) a positively charged ion, i.e. one that would be attracted to the cathode in electrolysis

Cationnoun

a positively charged atom, radical, or molecule, which in electrolysis migrates to the cathode; a positive ion; - opposed to anion.

Cationnoun

a positively charged ion
