In an incandescent light bulb, a positive and negative (or neutral wire) are connected by a tungsten filament in a vacuum. An electrical current passes through the thin filament, heating it very hot and causing it to glow. Eventually, after repeated use, the tungsten filament gets quite thin and eventually breaks, which is what happens when the light bulb burns out! Also, if the filament is exposed to oxygen while the current is flowing, the filament will break melts.
TIP: DON'T USE INCANDESCENT LIGHT BULBS... SWITCH TO ENERGY-SAVING COMPACT FLUORESCENTS!!!!
Actually most incandescent light bulbs have argon and nitrogen inside them. Early lightbulbs were vacuums.

∙ 11y agoIf you mean the bit that heats up and gives out light then it is call a "filament" from the Latin word Filum - a thread.
It is usually made from very, very thin Tungsten wire which is twisted into a long tiny spring which is then coiled up again so that it looks like thin wire. Very cool to see under a microscope.

∙ 13y agoWell if you are looking for the actual matter of which it is made, I believe it is tungsten, since it conducts heat very well

What is the wire inside a light bulb called?
filament
What light bulb number for a 99 Toyota Camry?
need more info. which light bulb? there are a hundred lights inside and out for a camry.
What does a light bulb have to do with an electrical light source?
A light bulb is a source of electric light. In an incandescent light bulb, the glass bulb forms a protective shield around a glowing filament. The air inside the glass bulb is removed, or replaced with an inert gas. Electric current is passed through a thin metal filament (usually tungsten), which causes it to glow white hot, giving out light. The protective bulb stops the filament from burning up, as it has no Oxygen.
Where does electricity come from inside a torch?
A tiny light bulb with a reflector is lit up with a battery. The switch connects the electric circuit; the power flows through the wire and the bulb lights up.Current through resistive filament of globe produces heat and light.Well first there's these two batteries inside it, then there's a wire inside it connecting it to the light bulb. then it makes one light bulb or more light by the energy of the battery. that makes the flashlight light. also there's a switch that connects a wire. if you pull the wire forward it will connect and make it light. but the opposite way makes the part of the switch go back and the light bulb won't light.
When was the light bulb first used in homes?
The first light bulb was invented around the 1850's or so when Benjamin Franklin discovered how electricity worked. His work was continued with light bulbs.
Is a light bulb evacuated?
Yes, the inside of a light bulb is a partial vacuum.
What is the resistor inside a light bulb called?
the wire in your light bulb is a resistor :)
If your brake lights work but not the tail lights and its not the fuse?
Have you checked your bulbs ? The tail light / brake light bulb has 2 wires inside it In my case I have had to change each bulb because the brake light portion did not work but the tail light portion of the bulb did ( I'm assuming that your front park lights are working )
How does fruit make a light bulb work?
The citric acid inside in a fruit could make it work. Fruits that is part of the citrus family has a contains a citric acid. For example a lemon, it could make a light bulb work. :)
What gas is inside a light bulb?
The kind of gas that is in a light bulb is called Argon.
What did Einstein do 100 times to get it to work?
To build the light bulb.
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.
On when the flashers work the back blinks real fast and the inside light doesn't come on?
Replace the bulb on the one that doesn't work.
What temperature does a filament inside a light bulb reach?
Answer:The filament inside the light bulb reaches over 3000 degree Celsius.
Does the middle bulb on the tail light work?
If there is a bulb, it should work.
What is the filament inside a light bulb?
Tungsten
How do you produce light bulbs in CO2?
You do not. CO2 has nothing to do with the creation of a light bulb. A typical incandescent bulb has a vacuum inside. No light bulb uses CO2.
