Potato Battery: Understanding Chemical and Electrical Energy
A potato battery is a type of battery that is known as an electrochemical cell. The chemicals zinc and copper (in the screw and penny/wire) react with each other, which produces chemical energy. This chemical energy is converted to electric energy by a spontaneous electron transfer. The potato acts as a buffer and an electrolyte for the two metals.
