Why do fruit batteries work?

Answer 1

Regular batteries work because of the electrical current that runs through them. Acidic fruits have particles which when charged up act as an electrical current allows them to work just like a normal battery.

Answer 2

All batteries work by creating molecular changes to the 2 main compounds involved, when one or both are surrounded by a third compound. These chemical changes cause electrons to flow from one to the other when there's a path creating electricity. Zinc is just another element that a reaction can be generated from. Once there isn't enough of the right molecule to loose electrons the battery is dead.

Of the batteries I am aware of Zinc is the material that looses electrons to create the flow.

Answer 3

Fruit batteries work due to the presence of citric acid and electrolytes in the fruit, which can create a chemical reaction with metals like zinc and copper. This reaction generates a flow of electrons, creating a small electrical current. This current can be harnessed to power small devices like LED lights or clocks.

Answer 4

They work, because if you put it in a fruit or juice (which contains acid) with another DIFFERENT metal.. it would go through the wire and light up a bulb or something...

Answer 5

In a battery there needs to be two metals (zinc and copper) and the zinc exchanges electrons and the energy released is what makes the power.

Answer 6

Zinc was the best of inexpensive metals at reacting with electrolytes to produce electricity. The metal 'Lithium' has become cheap enough these days to be utilized in even better power cells.

Answer 7

Zinc is used by batteries because the free electrons inside the atoms have a higher charge making them go faster causing a better battery life.
