Answer:
Voltaic cells convert chemical energy to electrical energy by means of an oxidation-reduction reaction. Electrolytic cells convert electrical energy to chemical energy, so they are the opposite of voltaic cells. They require an input of electrical energy to cause an oxidation-reduction reaction.
