WitrynaFor ‘impressed current’ CP, an inert (non-consuming) anode is used and the current is supplied by a rectifier. In this RP, the cathode of the electrochemical cell (i.e. the structure, sub-system or component to rece ive CP) is … WitrynaAn anode is an electrode of a polarized electrical device through which conventional current enters the device. This contrasts with a cathode, an electrode of the device through which conventional current leaves the device. A common mnemonic is ACID, for "anode current into device". [1]
