How does a fruit battery work?

A fruit battery works by using the acidic juice in fruit, such as lemons or Oranges, to facilitate a chemical reaction between two different metals, typically a copper electrode (cathode) and a zinc electrode (anode). The acid in the fruit acts as an electrolyte, allowing ions to move between the electrodes. This movement of ions generates a flow of electrons, creating an electric current. The more acidic the fruit, the better it can conduct electricity, enhancing the battery's output.
