What is a fruit battery?

Answer by  gaja (147)

It is a fun way to experiment with electricity. You need an acidic fruit(lemon, orange...), and two types of metal, e.g. a copper penny and a galvanized nail. Stick the two pieces of metal into the fruit (not touching each other) and wire them up to a low voltage light bulb.

It works on the concept of the voltaic cell. You need an acid fruit like orange, lime, or lemon and you should stick a copper and a zinc wire into it.
