Incandescent light bulb electrons
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… WebAn incandescent bulb is a light bulb that produces light by heating a thin wire filament to a temperature at which the filament glows, then causing it to give off light. The filament is heated to a temperature of about 2,600 …
