(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 can have either a negative or a positive voltage with respect to anode of the same polarized device (depending on whether the device is a load or a source, respectively).
Diagram of a copper cathode in a galvanic cell (e.g. a battery). Positively charged cations move towards the cathode allowing a positive current i to flow out of the cathode.
(electronics) The electrode from which electrons are emitted into a vacuum tube or gas-filled tube.
Glow from the directly heated cathode of a 1 kW power tetrode tube in a radio transmitter. The cathode filament is not directly visible.
(electronics) That electrode of a semiconductor device which is connected to the n-type material of a p-n junction.
The circuit diagram symbol for a diode.
