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.
A device that converts mechanical energy into electrical energy is called an Electric Generator. It works by inducing an electric current in a loop of wire by using magnetic fields.   An electrical generator or Dynamo.The mechanical energy moves a magnetic field relative to electric coils and creates electricity. Little Dynamos on bicycles provide light at night.t works by inducing an electric current in a loop of wire by using magnetic fields.   An electrical generator or Dynamo.
