Definition: electrode capable of emitting negative charge carriers to and/or receiving positive charge carriers from the medium of lower conductivity

NOTE 1 – The direction of electric current is from the medium of lower conductivity, through the cathode, to the external circuit.

NOTE 2 – In some cases (e.g. electrochemical cells), the term "cathode" is applied to one or another electrode, depending on the electric operating condition of the device. In other cases (e.g. electronic tubes and semiconductor devices), the term "cathode" is assigned to a specific electrode.
