a filament
Modern light bulb filaments are usually Tungsten not Carbon. However early bulbs used things like silk coated with Carbon. Filament means thin thread. The bulbs are filled with inert gas like Argon to stop the filament from burning up with oxygen. Arc lamps use Carbon rods though.
As an incandescent light bulb is used, tungsten slowly evaporates from the filament causing it to get thinner. When it gets too thin it can no longer carry the current and part of it melts causing the bulb to blow out.
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.
Any organic substance or sample thin enough to let light through.
"Friction" is used loosely here: this can more accurately be called electric resistance. "Friction" in the bulb filaments opposes current at a very minimal amount. This gives off heat, explaining why a bulb is hot. Also this "friction" prevents strong current from burning things out. All of our daily electrical appliances have tons of resistors in them.
Filament
The thin wire inside an electric bulb is called a filament. It is usually made of tungsten and becomes hot and emits light when an electric current passes through it.
Its a coiled tungsten filament.
A light bulb filament is a thin wire, typically made of tungsten, that is heated by an electrical current to produce light. As the filament heats up, it glows and produces light, making it a critical component in an incandescent light bulb.
The filament, located inside the light bulb, is made of a very thin wire usually made of tungsten. This filament is heated by the flow of electricity, causing it to emit light.
If you are talking about an incandescent light bulb then its called a filament. It is thin so that it has a high level of resistance. Current going through the filament causes it to heat up and give off EM radiation in the spectrum of visible light.
The long thin light bulb is called a fluorescent tube or a fluorescent light bulb. It is commonly used in commercial buildings, offices, and schools for general lighting purposes.
The glass around the bulb is thin to allow light to pass through easily. Thicker glass would absorb more light and reduce the brightness of the bulb. Thin glass also helps to dissipate heat generated by the bulb efficiently.
If the filament of a bulb is broken, it is referred to as a "burnt out" or "blown" bulb. This means that the filament, which is the thin wire inside the bulb that produces light when electricity passes through it, is no longer connected and the bulb cannot function properly.
A light bulb's filament is thin to increase its resistance, which produces heat and light when an electric current passes through it. The thin filament also allows for more surface area to emit light efficiently.
It is called a filament and usually made of tungsten steel.
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.
