Question

why is tungsten used for the filament in electric bulb?

Answer 1

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.

Answer 2

Answer:

hey mate here is ur ans...

Explanation:

tungsten is use as bulb filament due to following reasons,

1. having high melting point.
2. prevents from oxidation
3. good conductor of electricity
4. have low resistivity..
