|Definition:|| electrode capable of emitting positive charge carriers to and/or receiving negative charge carriers from the medium of lower conductivity
NOTE 1 – The direction of electric current is from the external circuit, through the anode, to the medium of lower conductivity.
NOTE 2 – In some cases (e.g. electrochemical cells), the term "anode" 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 "anode" is assigned to a specific electrode.
