Best Answer

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 part of the bulb glows to produce light?

the filament


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.


Which type of light bulb glows when a filament inside it gets hot?

An incandescent bulb.


What part of a light bulb is the filament?

It's the small coil of very fine tungsten wire that glows white hot.


What part of a light bulb has the most resistance?

the actual filament itself in a light bulb has the most resistance,this is why it glows and produces light,the rest of the bulb is sufficiently engineered to carry the voltage and current applied to it without producing too much heat.


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


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.


What happens to the electrical energy used to light a light bulb?

It heats the filament (which glows and so generates electromagnetic energy).


Why bulb glows continuously?

The bulb glows continuously probably, because the circuit it is installed in, is in the closed position.


Is circuit part of a light bulb?

A light bulb can be part of a circuit.
