Tungsten Filament
The tungsten filament of a vacuum incandescent lamp is heated to
temperatures where visible light is emitted by resistance heating.
Tungsten filament acts as an electrical resistor, which dissipates
power proportional to the voltage applied, times the current
through the filament. When that power level is sufficient to raise
the temperature to above ***0 degrees Kelvin, visible light is
produced.
