cathode (plural cathodes)
- (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.
- (chemistry, by extension) The electrode at which chemical reduction of cations takes place, usually resulting in the deposition of metal onto the electrode.
- (electronics) The electrode from which electrons are emitted into a vacuum tube or gas-filled tube.
- (electronics) That electrode of a semiconductor device which is connected to the n-type material of a p-n junction.
