It made the light bulb have light.
yes he improved the light bulb that Edison invented using the carbon filament.
James watt
the first one was carbon filament
Yes
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.

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.
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
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Edison can claim is the 'development' of a commercially useful light bulb using a carbon filament - though this was superseded by the tungsten filament not long after.
Thomas Edison is credited with inventing the carbon filament used in the first practical incandescent light bulb. He experimented with various materials before finding that carbonized bamboo was the most effective in producing a long-lasting light.
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.
