Why is tungsten used for lihjt bulb filaments?
Tungsten is used for light bulb filaments because it has a high melting point and can operate at high temperatures without degrading. This allows the filament to produce bright light while lasting longer than filaments made from other materials. Additionally, tungsten is ductile and resistant to oxidation, further contributing to its durability in light bulbs.
What is the wires inside a bulb called?
A filament.
How does bulb glow?
When electricity flows through the filament of a light bulb, it heats up the filament to such a high temperature that it begins to glow and emit light. This process is known as incandescence. As the filament glows, it emits light in the visible spectrum, allowing us to see.
Do you use pig hair to make a light bulb?
No, pig hair is not used to make light bulbs. Light bulbs are typically made using a combination of glass, metal, and tungsten or other types of filaments. Pig hair is not a suitable material for this purpose.
What 2 things did Edison make to make a filaments?
Edison made a carbonized cotton thread and a carbonized bamboo filament to improve the longevity of the light bulb. These materials were more durable and longer-lasting compared to previous filaments like carbonized paper or platinum.
What element are light bulb filaments made out of?
Tungsten, a metal with a very high melting-point.
What is first light bulb made out of?
It was thought that carbon would be the best material for filaments because it is the element with the highest melting point of 6,510 ºF.
What did Joseph swan make the light bulb out of?
He made it out of carbonized paper filaments in an evacuated glass bulb.

What mineral is used in tools and machinery?
The answer is iron. It is used to make steel for tools,machinery,and light-blub filsments. +++ Not the light-bulb filaments. They are made from tungsten.
What is the wires inside a bulb called?
A filament.
What is used to make globe filaments?
Globe filaments are typically made using tungsten, a strong and heat-resistant metal. The tungsten is coiled into a filament that can withstand the high temperatures required for efficient light emission in a globe-shaped light bulb.

What year did Lewis Latimer improve light bulb?
Lewis Latimer did not improve the light bulb. He patented a more efficient way to produce carbon filaments for light bulbs, which helped make them longer-lasting and more affordable. Latimer's improvements were made in the late 19th century, specifically in 1881.

What elements are in lightbulbs?
Tungsten is the element that the light bulb's filament is made from. The element's atomic symbol, W, comes from the word Wolfram, the original name for tungsten.
