Which fruit or vegetable can power a light bulb?

A lemon can power a light bulb due to its acidic content, which facilitates a chemical reaction between two different metals, typically copper and zinc, when inserted into the lemon. This reaction creates a flow of electrons, generating a small amount of electricity capable of lighting a low-voltage bulb. Similarly, other fruits and vegetables, like potatoes and Apples, can also be used to generate electricity through similar chemical processes.
