Why do apples produce electricity?

Apples produce electricity because of the acids in their juices. You can do experiments with lemons too because they have an extremely high acidic level. You could also say that the type of electricity that you are trying to describe could also be called power. It all depends on what context you are putting it into. By the way, I'm 11 almost 12 years old. You should have learned this if anyone reading this is younger than 11.
