I've read most of the popular books on they all refer to say Copper 180 Amps per square metre, that's fine, what I would like to know - Does 180 Amps go through the Anode? Or is is 180 Amps per Anode / Cathode face?
Sowden, Most are more interested in the cathode current density rather than anode current density, but I think people should specify more. These days 260 A/m² ore more cathode current density is not so uncommon. Yes, you have to consider the area of the electrode in the solution, so area per cathode = height x width x 2. To add to the confusion cathodes area often around 1 m² on each side, but not exactly (0.9 to 1.1 m²). No warranty on this information Adam
