How did thomas edison make the light bulb?
Thomas A. Edison, a young inventor working in Menlo Park, New Jersey, began working on his own form of electric light in the 1870s. In 1877 Edison became involved with the rush for a satisfactory electric light source, devoting his initial involvement to confirming the reasons for his competitors’ failures. He did, however, determine that platinum made a much better burner than carbon. Working with platinum, Edison obtained his first patent in April of 1879 on a relatively impractical lamp, but he continued searching for an element that could be heated efficiently and economically. Edison also tinkered with the other components of the lighting system, including building his own power source and devising a breakthrough wiring system that could handle a number of lamps burning at the same time. His most important discovery, however, was the invention of a suitable filament. This was a very thin, threadlike wire that offered high resistance to the passage of electric currents. Most of the
