USA HISTORY

Detailed explanation-1: -The incandescent lamp.In 1878–79 Joseph Wilson Swan in England and later Thomas Alva Edison in the United States independently invented a practical electric incandescent lamp, which produces continuous light by heating a filament with an electric current in a vacuum (or near vacuum).

Detailed explanation-2: -A significant invention of the late period of the Industrial Revolution was the light bulb, which was invented by Thomas Edison in 1879.

Detailed explanation-3: -By January 1879, at his laboratory in Menlo Park, New Jersey, Edison had built his first high resistance, incandescent electric light. It worked by passing electricity through a thin platinum filament in the glass vacuum bulb, which delayed the filament from melting.

Detailed explanation-4: -His contributions to engineering helped bring technology into the electric age. The most inventive electrical engineer in history before “electrical engineers” really existed, Thomas Edison (1847-1931) created and improved many 19th and 20th Century gadgets from the telegraph to electric cars.

Detailed explanation-5: -When Thomas Edison demonstrated the first practical incandescent light bulb on New Year’s Eve 1879, it marked the dawn of the electric age.
