Sir Humphry Davy conducted a series of experiments to investigate the nature of electric charge. He developed theories about positive and negative charges, and discovered that electric current could be used to decompose substances. In his experiments, Davy used voltaic piles, which were the first batteries, to create a steady electric current. He also used mercury, zinc and other metals to conduct his experiments. His discoveries paved the way for the development of modern batteries and electricity generators.
