Does current flow from anode to cathode?
Does current flow from anode to cathode? The ELECTRONS will go from anode to cathode. In an electrolytic cell, it is the opposite. The anode is positive and the cathode is negative, so the current goes from anode to cathode. Do electrons flow in galvanic cell? Electrons flow from the anode to the cathode through […]
