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.

What is the function of the Tungsten filament in a light bulb?
Because it has a very very high melting temperature: 6191F, 3422C. However it is also very difficult to work with, so early light bulbs used carbon for making the filament instead. Around the year 1900, carbon filaments were replaced with tantalum filaments. It was not until about 1910 that it became practical to make tungsten filaments.
How do the makers of light bulbs prevent filaments from burning out?
When the glass is sealed on the light in the build process the light is filled with an 'innert' gas. That means that the gas will not sustain fire or ignition.
What book has plane models from ancient Egypt and about Bermuda triangle and has hieroglyphics of Egyptians holding light bulbs?
Technology of the Gods by David Hatcher Childress. The light bulbs with snake-llike filaments appear to be fluorescent types, which did not exist until about l9l5 at the earliest!
Are light bulbs fragile?
why light bulbs are fragile
Do light bulbs emit light or suck dark?
Light bulbs emit light.
What metal use the filaments in light bulbs?
Tungsten is used in filaments of light bulbs.
The element used in light bulbs filaments?
Tungsten
What elements are in light bulbs as a filament?
Light bulb filaments are usually made of tungsten, which has a very high melting point. Occasionally carbon is used as a filament.
Element used in light bulb filament?
That depends on the bulb, and the time frame. The first bulbs had carbon filaments. Certain bulbs used in control devices have iridium filaments. Modern grocery store incandescent bulbs have tungsten filaments.Tungsten, because of its very high melting point.
Which element is used in the filaments of household light bulbs?
usually tungsten
What element makes up the filaments in light bulbs?
It is usually Tungsten.

What are hair like filaments of fungi?
In an incandescent light bulb (the kind that screws into a standard light socket), the filament is the piece of metal in about the middle of the glass bulb that glows and emits light and heat when electricity passes through it. It is usually made of tungsten, but originally was made of carbon. New compact fluorescent and LED-based light bulbs do not really have filaments like incandescent light bulbs. Filament is a term also used in astronomy and biology for different things, but these uses are not as common as in light bulbs.
What element is commonly found in filaments in incandescent light bulbs?
Tungsten, as it burns long and brightly.
Why do light bulbs use led?
no they are two different things....LED use semiconductors for light production...whereas bulbs use filaments....nothing uses any other...
Is carbon wire still in light bulbs?
Modern light bulbs are made of tungsten wire.
How many filaments exist in a light bulb?
Most incandescent bulbs have one filament. Some halogen bulbs working on 240 v have two filaments in series, which must be to simplify manufacture of bulbs being made for 120 v and 240 v in the same factory.
