Detailed explanation-1: -According to the Thomas Edison National Historical Park, “In 1879, he made an incandescent bulb that burned long enough to be practical, long enough to light a home for many hours.
Detailed explanation-2: -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. Still, the lamp only burned for a few short hours.
Detailed explanation-3: -In the case of the light bulb, Edison may have been convinced that he could make a large amount of money by creating a new product which could replace gas lighting. He set to work on such a light source, devising a bulb using filaments made of carbon. His first successful product was patented in 1879.
