Did Lewis Howard Latimer light bulb with a carbon filament?
yes he improved the light bulb that Edison invented using the carbon filament.
Why are V-i characterstics different for tungsten and carbon lamp?
As carbon filament bulbs have a negative temperature coefficient and tungsten filament light bulbs have a positive temperature coefficient.
Who invented the carbon filament for the electric light?
James watt
What did early light bulbs have inside them?
the first one was carbon filament
Do carbon filament light bulbs save more energy?
Yes
Who invented the carbon filament a part of the light bulb?
Joseph Swan
What are carbon filaments for light bulbs?
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 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.
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Edison can claim is the 'development' of a commercially useful light bulb using a carbon filament - though this was superseded by the tungsten filament not long after.
In 1881 who perfected light bulb by adding carbon based filament?
Lewis Howard Latimer
What part of the light bulb did Lewis Latimer invent?
Do a search on Wikipedia.
What is used to make globe filaments?
The first successful light bulb filaments were made of carbon (from carbonized paper or bamboo). In 1902 the Siemens company developed a tantalum lamp filament. From 1898 to around 1905 osmium was also used as a lamp filament. In 1906 the tungsten filament was introduced
