Explanation:
In 1802, Humphry Davy invented the first electric light. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. His invention was known as the Electric Arc lamp. And while it produced light, it didn't produce it for long and was much too bright for practical use.
