3. How a Fruit Battery Works
Zinc
Copper
The electrons flow towards the copper when the fruit battery is connected in a circuit – this creates electrical energy!!!
Hydrogen gas
A transfer of electrons (chemical reaction) occurs between the zinc and the acid in the fruit. This reaction results in hydrogen gas from the acid and extra electrons from the oxidized zinc. (This will happen with or without the copper nail). The copper nail helps draw power from the fruit and channel electrons through an external circuit.
