Science glossary film: Electrode

An electrical conductor that connects to a nonmetallic part of a circuit. In electrolysis the electrodes are rods inserted into the solution and connected to an external power source. In a typical electric cell, electrodes make contact with a chemical mixture in the cell. And in medical equipment electrodes can connect metallic wires to skin.
