anode
IPA: ˈænoʊd
noun
- (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 positive or a negative voltage with respect to cathode of the same polarized device (depending on whether the device is a load or a source, respectively).
- (chemistry, by extension) The electrode at which chemical oxidation of anions takes place, usually resulting in the erosion of metal from the electrode.
- (electronics) The electrode which collects electrons emitted by the cathode in a vacuum tube or gas-filled tube.
- (electronics) That electrode of a semiconductor device which is connected to the p-type material of a p-n junction.
