RE: Tech Review Contest: I review a Bulb!

in Zero to Infinity3 years ago

Bulbs were not in use until in 1802 when Humphry Davy inverted the first electric bulb. It was initially powered by battery, and it works until in 1840. British scientist Warren de la Rue enclosed a coiled filament in a vacuum tube and passed electricity through it. It kept developing from the first design until 1878 when Thomas Edison carry out a research to produce the first incandescent lamb. Bulbs then evolved from there and we find them useful till date. There
have been various type which has come from Humphry Davy, and we can refer to him as the Father of bulb.
