tungsten filament is used in bulb because
-----------------------
it has a very high melting point and it does not melt very easily at very high temperatures as in order to emit light the filament should be at a very high temperature and if the filament has low melting point the filament will melt and the bulb wont work anymore therefore tungsten is used as a filament
