Background
The first electric light was made in 1800 by an English scientist named Humphrey Davy. He invented an electric battery after experimenting with electricity. He connected wires to his battery and a piece of carbon, and the carbon glowed. This produced light. In 1860, an English physicist named Sir Joseph Wilson Swan wanted to find a practical and long-lasting electric light. He found that a carbon paper filament worked pretty well in terms of producing light, but it burned up quickly.Swan demonstrated his new lights in 1878 in Newcastle, England. In 1877, Charles Francis Bush manufactured some light bulbs for a public square in Cleveland, Ohio. They were only used by a few people.
