How do you draw a cell diagram in chemistry? Why do electrons flow from anode to cathode? By definition, a cathode is a negatively charged electrode (a metal plate or a wire), and an anode is a positively charged electrode. Therefore, electrons are repelled by the cathode and are attracted to the anode, which results in the current of electrons flowing from the cathode to the anode.
