Tungsten metal is used for making the filament of electric bulbs.
Tungsten is used to making an electrical bulb filament for the following properties:
It has a very high melting point being an alloy.
It has very high resistance, so it does not burn easily at room temperature.
The lamp glows at high temperatures. >
Tungsten filament does not melt even though a significant amount of heat is generated due to the passing of the current through the filament (through the heating effect of the current).
An incandescent light bulb is an electrical light with a wire filament that is heated until it glows.
The filament is wrapped in a bulb of glass to shield the filament from oxidation. Current is supplied to the filament by means of terminals or wires inserted in the glass.
The incandescent bulb has been commonly used in household and commercial lighting, for portable lightings such as car headlamps, table lamps and flashlights, and for decorative and advertisement lighting.
