The first commercially successful light bulb filaments were made from carbonized paper or bamboo. Carbon filaments have a negative temperature coefficient of resistance—as they get hotter, their electrical resistance decreases. This made the lamp sensitive to fluctuations in the power supply, since a small increase of voltage would cause the filament to heat up, reducin… WebNov 8, 2009 · By the time he died at age 84 on October 18, 1931, Thomas Edison had amassed a record 1,093 patents: 389 for electric light and power, 195 for the phonograph, 150 for the telegraph, 141 for ...
