Why is tungsten used for the filament in electric bulb?
Answered by admin @
The filament used in an electric bulb has to get heated up to a very high temperature in order to emit light.
if a filament of low melting point is used it will melt and the bulb will become useless.
therefore wires of high melting points are preferred.
tungsten has a very high melting point, therefore, it is used as a filament in the electric bulb.
