Relating to or occurring at an anode; involving the positive electrode in electrical systems.
From Greek 'anode' (way up, from 'ana-' up + 'hodos' path) plus '-al' (relating to). The anode is where electrons exit in electrolysis.
In a battery or electrical circuit, the anodal side is where the positive charge lives—it's the opposite of the cathode. Understanding 'anodal' helps explain how electroplating and rust prevention work.
