The potatoes don't provide any energy. That's a common misconception, the energy actually comes from the two electrodes. The potato just acts as a salt bridge and ion supply. You see, when the two different metals are stuck into the potato, one of them releases positive ions into the liquid in the potato more easily than the other.
Table salt releases two electrically charged ions-a sodium ion with a positive charge, and a chlorine ion with a negative charge. To make a battery with a potato, you need to put two different metals into the potato...the metals can be zinc and tin, or copper and steel, or other choices.The point is-the two metals have to be different metals.You might use a penny (made of copper) and a nickel (made of...ummm...nickel).able salt releases two electrically charged ions-a sodium ion with a positive charge, and a chlorine ion with a negative charge.
