+“lemon battery” is, a battery built from lemons. Here the electricity is generated from a chemical reaction between acids and two electrodes of different metals – zinc and copper. Placed within one small or several normal-sized lemons, the setup is identical to Volta's electrical battery. In the lemon battery, the copper serves as the positive electrode, while a piece of zinc acts as the negative electrode. Citric acid triggers the chemical reaction between the negative and positive electrodes, generating a small potential difference, which, in turn, becomes the electrical current. The electric current could also be produced by, for example, potatoes, or humans.
