What is the color of the filament as you dim the bulb

  • A filament of different wavelengths and colors  irradiates the radiation from the black body.  The strength peaks  with a temperature-dependent wavelength.  The peak of the bulb is dimmed and the color goes  from white to brown, due to its length of longer wavelengths.

  • The "Heat" in the filament you're writing about is there because the electrical current  is flowing through that filament, making it so hot, the filament "white hot" glows.  So if we turn the switch "on" current through the wire of the filament, and  there's so much resistance to the flow that the wire begins to shine white hot.  If we turn the off" key, the current stops  flowing, and the filament wire cools down to room temperature.
