In an incandescent lamp, it is called a filament. It is usually made out of Tungsten. The resistance in the filament causes it to heat up, and then glow.
In a neon lamp it is plasma, which is an ionized gas. In a fluorescent bulb Mercury vapor is ionized to produce UV radiation, that hits the phosphor coating on the outside of the bulb and that glows.

What does 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 definition of electric bulb?
A glass sphere containing a metal element that glows when electricity is applied.
What part of a circuit is the light bulb?
It has components that are arranged end to end in order to produce light.
What is the input or output of the light bulb?
Input to light bulb is Electricity and output is light.
When and where did Thomas Jefferson invent the light-bulb?
Thomas Jefferson did not invent the light bulb. The light bulb was invented by Thomas Edison in 1879 in New Jersey.
What part of the bulb glows to produce light?
the filament
What is the name of the part of a light bulb that glows?
The part of a light bulb that glows is called the filament. It is typically made of tungsten and emits light when an electrical current passes through it, heating it up to produce light.
Is there gas when you turn on a light bulb?
yes, there is a gas in a light bulb you energise it and it glows.
What part of a light bulb is the filament?
It's the small coil of very fine tungsten wire that glows white hot.
What is the thin wire is an electric bulb that glows called?
The thin wire in an electric bulb that glows is called a filament. It is typically made of tungsten and glows when electricity passes through it, producing light.
Where is there a resister in a light bulb circuit?
In an old-fashioned light bulb, the part that emits light is a resistance. When current flows through it, it heats up so much that it glows - it emits light.Due to their lousy efficiency, these light bulbs should be discarded, in favor of fluorescent light bulbs or LED light bulbs.In an old-fashioned light bulb, the part that emits light is a resistance.

When a fluorescent light bulb glows what state of matter is it?
it is plasma , gas and liquid
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.
Which type of light bulb glows when a filament inside it gets hot?
Incandescent light bulbs produce light when a filament made of tungsten wire is heated by an electric current flowing through it. The filament glows and emits light as it reaches high temperatures.
What is something created when filament that becomes so hot it glows?
A light bulb is created when a filament becomes so hot that it glows. The high temperature causes the metal filament to emit light, which produces illumination in the bulb.
Is a light bulb a soure of light?
Yes, a light bulb is a source of light. When current is going through the filament the resistance generates enough heat that the filament glows, producing light.
Why does a fluorscent light not work in the cold?
fluorescent bulbs have mercury in them. There are heaters at the ends of the bulb that vaporizes the mercury to allow the light to be produced ( the fluorescence on the inside of the bulb is what actually glows). If the bulb is cold you do not get the ionization of the mercury to cause the fluorescent powder inside the bulb to glow, or it just glows a small amount.
