Origin of electrodecoined by Michael Faraday from electr(o)- + -ode
- A solid electric conductor through which an electric current enters or leaves an electrolytic cell or other medium.
- A collector or emitter of electric charge or of electric-charge carriers, as in a semiconducting device.
The word was coined by the scientist Michael Faraday from the Ancient Greek words ἤλεκτρον (ēlektron, “amber”) (from which the word electricity is derived) and ὁδός (hodos, “way”).
electrode - Computer Definition
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. See battery, air interface and cathode.
