Because of these it can reach high temperature before melting. The reason tungsten is used is because it has the highest melting temperature of any element at 3600k.

A Fused Electric Bulb Has Its Filament Cut Why My Q A Corner

The filament of an electric bulb is made of tungsten.

An electric bulb has a filament made of. 1906 william coolidge developed ductile tungsten from sintered tungsten for making filaments. Filaments in incandescent light bulbs are made of tungsten. Hence the filaments are made of tungsten.

For a typical incandescent light bulb the tungsten filament operates at approximately 2500 celsius. The tungsten is arranged in a double coil in order to fit it all in a small space. Whenever an electric current goes through the filament the filament glows.

1911 general electric company started marketing first incandescent bulbs made of ductile tungsten. I a wire made of tungsten is used for filament of electric bulb because it has a high melting point and high resistivity. Ii a nichrome wire is used as a heating element for a room heater because the resistivity of nichrome is high and increase in its value with increase in temperature is high.

It may also be known as the electron emitting element in a vacuum tube. The filament of an electric bulb is made of tungsten because it has some amazing properties including the highest melting point 3422oc lowest vapor pressure and greatest tensile strength out of all the metals. The filament in a light bulb is made of a long incredibly thin length of tungsten metal.

That is the filament is wound up to make one coil and then this coil is wound to make a larger coil. An incandescent light bulb incandescent lamp or incandescent light globe is an electric light with a wire filament heated until it glows. To make the bulb produce more light the filament is usually made of coils of fine wire also known as the coiled coil.

The filament is enclosed in a glass bulb with a vacuum or inert gas to protect the filament from oxidation current is supplied to the filament by terminals or wires embedded in the glass. In a typical 60 watt bulb the tungsten filament is about 6 5 feet 2 meters long but only one hundredth of an inch thick. 1917 a coiled coil filament was developed and patented by burnie benbow.
