Review of Literature
A voltaic battery is a battery consisting of a number of Primary cells with two or more unlike electrodes. Batteries produce electricity when two or more Primary or Secondary battery cells convert chemical energy to electrical energy. Fruit can be used as batteries. The acid in fruit reacts with water to create hydrogen. The hydrogen is in the forms of ions. Ions are positively charged atoms that are missing electrons. This enables the acid to take electrons from a metal, so an electrical charge or voltage is built up. The fruit with the highest amount of acid will generate the highest voltage.
