USA HISTORY

Detailed explanation-1: -On January 27, 1880, Edison received the historic patent embodying the principles of his incandescent lamp that paved the way for the universal domestic use of electric light. The patent number for his electric lamp is 223, 898.

Detailed explanation-2: -Edison was trying to come up with a high resistance system that would require far less electrical power than was used for the arc lamps. This could eventually mean small electric lights suitable for home use.

Detailed explanation-3: -Thomas Edison used this carbon-filament bulb in the first public demonstration of his most famous invention-the light bulb, the first practical electric incandescent lamp. The light bulb creates light when electrical current passes through the metal filament wire, heating it to a high temperature until it glows.

Detailed explanation-4: -On New Year’s Eve 1879, after toiling in his laboratory for over a year, Thomas Alva Edison unveiled his electric light bulb to the public in his hometown of Menlo Park, New Jersey. The very bulb is on display at the Smithsonian’s National Museum of American History.
