Assembly Method: Insert the copper and zinc plates into a piece of fruit. The copper plate serves as the positive electrode (anode) and the zinc plate as the negative electrode (cathode) of the fruit battery. Create multiple combinations and connect them in series or parallel to generate a larger current.

Principle: Copper and zinc exhibit different electrochemical activities. The more active zinc plate displaces hydrogen ions from the fruit's acidic components, generating positive charge and forming a galvanic cell. Each cell produces approximately 0.8V, resulting in a total voltage of about 3V for a 4-cell setup. The current strength directly correlates with the acid concentration of the fruit, observable through experiments (e.g., by monitoring the brightness of a light bulb). Suitable fruits include: lemons, limes, apples, pears, pineapples, potatoes, and even cola.
