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… WebIncandescent lamps produce light by using electricity to heat a thin strip of material called a filament. The filament resists the flow of electrons and this resistance heats up the filament until it glows. The color of this glow depends on the temperature, since the filament becomes a black body radiator.
