A filament radiates black-body radiation, with a range of wavelengths and colours. The intensity peaks at a wavelength that depends on the temperature. As the bulb is dimmed the peak radiation occurs at longer wavelengths and the colour goes from white to brown.

What is filament shaped into?
Bulb's filament are wounded into a coil.
Why does a fused bulb not glow?
A fused bulb does not glow because the filament of a fused bulb is broken. Since current can't flow through the filament, it can't get hot enough to glow.
What do the support wires do on a light bulb?
As the name implies, support wires support the filament wire in the bulb, The filament, of course is the wire that glows white hot, giving out light
What is the insulator in a light bulb?
Glass is the insulator in a light bulb. The base has a heavy piece of glass to separate the ring from the center, and there is a glass support inside the bulb to hold up the filament and separate the wires going to the filament.
What is the name thin wire inside a light bulb?
a filament
Why would a light bulb contain more than one filament?
In a lamp you can have three settings with two filaments. One filament is for dim. When it is on, the bulb is dim. One filament is medium. When only it is on, the light is medium. When both filaments are on, the bulb is bright. In auto and motorcycle applications headlamps can have 2 filaments. A 'dip' beam and a 'High' or 'Main' beam. When the High Beam is on the Dip is off and vice versa.
Is line spectrum obtained from filament of bulb?
filament of bulb
Which is more powerful a torch bulb or a mains filament bulb?
Mains filament
What is filament in a bulb?
The filament is the small coil that glows when the bulb is on. I believe its made out of tungsten
What is filament shaped into?
Bulb's filament are wounded into a coil.
Which is more powerful a torch bulb or a mains filament lamp?
Mains filament
What type of light is a light bulb that uses a filament?
A light bulb that uses a filament is also known as an incandescent light bulb.
Will bulbs be easier to operate when the higher the input current?
Higher input current means higher voltage. A bulb contains one filament (tungsten) when input power supply passing through this filament, the filament gets hot and makes a red color and then yellow. This filament needs only electrons flow, but if we are operating higher current bulb efficiency will down, when the filament burns out.
Which has the thickest filament - a high-resistance or a low-resistance bulb?
A low resistance bulb has a thicker filament.
What is the wire inside a light bulb called?
filament
Dim fluorescent bulb?
No...
What the filament of bulb is broken then it is called?
Fused bulb
