The cathode serves as the positive terminal and the anode as the negative terminal. The flow of electrons is from the cathode to the anode.The relationship between a cathode and an anode involves electrons. An example of this is reaction that takes place in an electrolytic cell. It has a cathode compartment, an anode compartment and a salt bridge that divides the compartment. The movement of electrons is from the cathode to the anode.
