It conducts electricity and has a very high melting point, thus it will not melt in high temperatures in light bulbs. In fact, tungsten has the highest melting point of all metals, at about 3400 degrees celcius.
In the old style filament lightbulbs it was tungsten (wolfram).
Tungsten is commonly used as the filament in incandescent light bulbs because of its high melting point and durability.
Electricity creates heat when flowing through a resistor such as the filament in a tungsten light bulb, and, since the heat can not be readily conducted away in the near vacuum inside a light bulb, the heat eventually raises the temperature of the filament to a value that leads to radiation of light from the hot filament.
Tungsten atoms evaporate from the filament of a bulb due to a process called sublimation, where solid tungsten directly turns into vapor without first becoming a liquid. This occurs because the filament of the bulb reaches extremely high temperatures during operation, causing the tungsten atoms to gain enough energy to break free from the solid structure and evaporate into the bulb's atmosphere.
An electric current passes through a very thin filament of tungsten, which to some degree resists the current and heats up until it glows brightly. Other substances could be used, but tungsten has the advantage of having an extremely high melting point and staying strong at high temperatures.
I believe it is tungsten.
The metal is Tungsten.
The material used in the construction of a light bulb filament is typically tungsten.
Usually tungsten.
Tungsten is an element. It is used in bulbs
In the old style filament lightbulbs it was tungsten (wolfram).
What is Tungsten
Tungsten is commonly used as the filament in incandescent light bulbs because of its high melting point and durability.
Tungsten filament is used in the creation of the light bulb. It can be made in different shapes like coiling, and horizontal or vertical helix.
The filament is the small coil that glows when the bulb is on. I believe its made out of tungsten
The filament in a light bulb is typically made of tungsten.
