How to Define Anode and Cathode ThoughtCo

Nov 21, 2019· Flow of Current . The anode and cathode are defined by the flow of current.In the general sense, current refers to any movement of electrical charge. However, you should keep in mind the convention that current direction is according to where a positive charge would move, not a negative charge. So, if electrons do the actual moving in a cell, then current runs the opposite direction.
