What did Thomas Alva Edsion invented?
Filament bulb
Who invented the carbon filament for the electric light?
James watt
When were filament tubes invented?
The first hot filament diode tube was invented in 1904 by Fleming, the first hot filament triode tube was invented in 1907 by DeForest. However it was not until 1913 that it was determined that high vacuum was actually needed for efficient and reliable operation of these tubes. So true hot filament vacuum tubes were not made and used until 1913.
Who invented the incandescent filament electric light bulb?
Thomas A. Edison
Did Lewis Howard Latimer light bulb with a carbon filament?
yes he improved the light bulb that Edison invented using the carbon 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Edison can claim is the 'development' of a commercially useful light bulb using a carbon filament - though this was superseded by the tungsten filament not long after.
What parts do you need to make a lightbub glow?
You need a filament, and then you run the electricity though it. The filament is made up of thin wire, but modern technology has given us the use of mercury or fluorescence in place of the filament (which would be an ionized gas).
Who invented the light bulb filament?
Thomas Edison is credited with inventing the first practical incandescent light bulb filament in 1879. He used a carbonized bamboo filament that gave the bulb a longer-lasting and brighter light compared to previous designs.
Which country invented the modern computer?
The Computer Modern was invented 1958 USA
Is the light bulb that Thomas Edison invented still lit to this day?
No, the original light bulb that Thomas Edison invented is not still lit today. The filament in the bulb would have burned out a long time ago. However, there are modern versions of light bulbs that are based on Edison's original design.
Who invented the long lasting filament electric light bulb?
Thomas Edison is credited with inventing the long-lasting filament electric light bulb in 1879. He developed a carbonized bamboo filament that could last for up to 1200 hours, making light bulbs practical for everyday use.
What devices control x-ray tube filament current?
The filament current of an x-ray tube is primarily controlled by a filament transformer, which adjusts the voltage and current supplied to the filament. Additionally, a rheostat or variable resistor may be used to fine-tune the filament current for optimal electron emission. In modern systems, electronic control circuits can also regulate the filament current more precisely, ensuring consistent performance and improved image quality. These devices work together to ensure the correct heating of the filament, enabling effective x-ray production.
