A device that emits, controls or receives electricity. Typically an end point or wire made of metal or some composite material, there are countless electrodes in electrical and electronics products. For example, in a vacuum tube, the cathode emitter is a "negative" electrode. The transparent wires made of indium-tin-oxide (ITO) that cross an LCD screen are electrodes.
