it is made of tungsten and is a resistor when current flows thru it it heats up and glows
A light bulb that uses a filament is also known as an incandescent light bulb.
It is the extremely thin wire inside the bulb. It is so thin that when the electricity goes through produce light, when that filament breaks the bulb is not good.
Answer:The filament inside the light bulb reaches over 3000 degree Celsius.
A light bulb works by passing an electric current through the filament, which is usually made from a high resistance substance such as tungsten. When the current flows through, the filament glows which produces the light. When it burns out, no electricity passes and no glowing occurs. Source: i just know
Technically the bulb does not light, it is but a housing for the filament and electrodes. It is the filament that gives off the light as it is heated by the electricity passing through it. The bulb helps to scatter the light in equal proportions.
A light bulb that uses a filament is also known as an incandescent light bulb.
In an incandescent light bulb the wire that gives off the light is called the Filament.
The filament of a light bulb overs enough resistance to current flow, that the filament heats up so much that it will glow and produce visible light.

light bulbs have metal contacts that connect to an electrical circuit and a filament. power lights up the filament in the bulb .
What is Tungsten
filament
filament
Electricity goes through the "electrical foot contact", heats up the wires (connected to the tungsten filament) therefore lighting the light bulb up. The filament is supported by wires. The glass mount holds up the two wires connected to the filament. That is how I think the light bulb works. Have a look.
All kinds of incandescent lamp, and all types of light bulb contains filament. But there are several kinds of filament applied each type of light bulb.
