Tugsten metal has melting point that is 3300 degree celsius .it can\’t be melt easily .Its also have a high resistivity since this metal is choosen as filament for bulb.
Tungsten metal is selected for making filaments of incandescent lamp bulbs because tungsten can sustain high temperatures and it has high melting point, combined with the fact that it also has high resistivity.
Yes,same and it is also a good conductor..
Beacuse it has high melting temperature..
