What is a potato and how can it make a voltage?
A potato is a South American herb that is a member of the nightshade family. People eat the starchy tuber of the vegetable. So how can a potato create a voltage? Potatoes contain phosphoric acid. It's the acid in the potato that allows a chemical reaction to take place. The potato battery works when a copper penny and a zinc-coated nail are placed in contact with the phosphoric acid inside the potato. The nail and the penny become the battery's terminals or electrodes. The acid reacts with the copper and removes electrons. The copper penny ends up missing some electrons, which gives it a slightly positive charge. The acid also reacts with the zinc nail. In this case the acid dissolves the zinc and leaves some of its electrons behind on the nail. The excess electrons on the nail and the lack of electrons on the penny result in the creation of voltage in the system. If the nail and the copper penny are connected together with a wire, the excess electrons move from the zinc nail to the positive charge on the penny. These moving electrons are called electrical current.

What was the potato clock invented for?
Patato clock was invented by William A. borst in1983.He was helping his stepdaughter in her science project when he was reminded of one of his physics class in which potatoes were used to generate energy. William fixed two metal prods into a potato and potato battery was made ready to generate energy.
