A carbon filament is primarily made of carbon, often in the form of graphite. It is produced by heating carbon-containing materials, such as cellulose or polyacrylonitrile (PAN), to high temperatures in a process called carbonization. This process removes non-carbon elements, resulting in a material that has high electrical conductivity and thermal stability, making it suitable for applications like light bulbs and electronic devices.
What else can I help you with?
What do the wires in the middle of a light bulb do?
The filament is made of tungten and these 'wires' (filament) conduct electricity.
Who invented the tungsten filament lamps?
Thomas Edison It was actually Irving Langmuir (of General Electric), also an American. Edison's incandescent lamp used a carbon filament, as did that of his contemporary, England's Joseph Swan who got there before Edison (who invented a longer lasting carbon filament). William Coolidge improve on Langmuir's filament by making it longer (the familiar twisted shape) and brighter. Humphrey Davy had invented a platinum filament way back in 1809 that worked, but was too expensive for commercial use. Those that followed him failed to cotton on to the use of a metallic filament and went for carbon instead. What Tomas Edison can claim is the 'development' of a commercially useful light bulb using a carbon filament - though this was superseded by the tungsten filament not long after.
What supports the anther?
The Filament
The vegetative filament is known as what?
The vegetative filament is known as a hypha. It is a tubular structure made of fungal cells that grow and spread to form the mycelium in fungi.
What is the wire inside a light bulb called?
The wire inside a light bulb is called a filament. It is typically made of tungsten and emits light when an electric current passes through it, heating it up to produce light.
How was the carbon filament a help to people?
It made the light bulb have light.
Did Lewis Howard Latimer light bulb with a carbon filament?
yes he improved the light bulb that Edison invented using the carbon filament.
Difference between tungsten lamps and carbon lamps?
tungsten lamp has got inert gas argonsometimes iodine is added to improve intensity carbon filament produces less light than tungsten lamp but it radiates much less energy in the form of heat waves
Sentence with filament?
Filament was made from plastic. The filament was very stable and smooth.
What is a filament made from?
A filament can be made from various materials such as plastic (like PLA or ABS), metal (like aluminum or titanium), or composite materials (like carbon fiber or wood). The choice of material depends on the intended use and properties needed for the final product.
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.
What is the filament in a light bulb made of?
The filament in a light bulb is typically made of tungsten.
What are the bulb of light bulbs made of?
Light bulbs typically contain a tungsten filament inside the bulb, which is enclosed by a glass envelope. The glass envelope is made of silica (silicon dioxide), which provides thermal insulation and protection for the filament while allowing light to pass through.
Who invented the carbon filament for the electric light?
James watt
What is metal with which the filament is made?
Assuming you're talking about light bulbs... the filament is made from Tungsten.
What is the filament in an incandescent light bulb made of?
The filament in an incandescent light bulb is typically made of tungsten.
What did early light bulbs have inside them?
the first one was carbon filament
