What is a filament that glows white hot in electric light bulbs?
Tungsten :)
Why do light bulbs use very fine filaments?
Incandescent light bulbs use tungsten( a metal which can withstand very high temperatures) as filament.When heated to a very high temperature, the filament glows emitting light and heat. Heating effect in filaments is caused by the property of resistance in conductors. On reducing the cross- section area( thickness) of the filament, its resistance is increased and hence the filament glows with comparitively lesser electric current.
What is the strip of material that glows in a light bulb called?
The strip of material that glows inside a light bulb is called the filament. It is usually made of tungsten and emits light when an electric current passes through it, heating it to a high temperature, causing it to glow and produce visible light. The filament is a crucial component in incandescent light bulbs, which have been widely used for many years, although more energy-efficient lighting technologies, such as LED (Light Emitting Diode) bulbs, are becoming increasingly popular
Why does the light bulb not work when the filament is broken?
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
Is a filament of a light bulb glows when an electric current flows through it is a chemical change?
It is a physical change brought about by the exitation of molecules producing heat and light. A general rule of thumb is that a physical change can be repeated on an article and chemical change cannot. Remove the current from a filament and it is still a filament.

Why scientists use tungsten metal in manufacturing the filament of the light bulbs?
it glows and emits light.

What type of light build glows when a filament inside it gets hot?
Electric lamps having incandescent filaments.
How does electricity work in light bulbs?
The wiring inside the light bulb is very thin (the filament) and glows when heated. The current through the thin wire heats up the filament wire so that it will glow. See the related link 'How Light Bulbs Work'.
Why do light bulbs produce heat or light?
The electric current heats up a filament inside the bulb so hot that it glows. Most of the energy produces heat and the remainder light. The inert atmosphere inside the bulb extends its life. The filament is made of a high temperature material like Tungsten
What is the wire inside an electric bulb known as?
This was called a filament and was found in older electric light bulbs.

How do light-bulbs work?
An electric current passes through a thin filament, heating it until it produces light. The enclosing glass bulb prevents the oxygen in air from reaching the hot filament, which otherwise would be destroyed rapidly by oxidation.
What makes up the filament of light bulbs?
Filament of light bulbs are made up of Tungsten.
The wire inside an electric bulb is known as the what?
This was called a filament and was found in older electric light bulbs.
What part of the bulb glows to produce light?
the filament
