What makes the fruit charge the iPhone?

Answer 1

The fruit can charge the iPhone through a process called electrochemical reaction. When two different types of metals (like copper and zinc) are inserted into the fruit, they create a chemical reaction that generates a flow of electrons. This flow of electrons produces a small amount of voltage, which can be harnessed to charge the iPhone when connected to the appropriate circuitry. However, the amount of charge generated is minimal and not practical for regular use.
