The potato battery is classified as an electrochemical cell, that converts chemical energy into electric energy through the transfer of electrons. When copper and zinc plates are inserted in the potato, a reaction occurs. The reaction is called Redox (Reduction-Oxidation). The water and the electrolytes in the potato allow electrons to flow from copper to zinc creating small electric currents. In this reaction, copper is being reduced and zinc is being oxidized. With the help of the wire, electr
