the filament of bulb is made from tungsten. Tungsten has the higgest melting point of approx 3400 degree celcius
If a low melting point filament is used there are chances of bursting
so its good to use filament with high melting point

Hey.... You can find the answer of this question on Brainly too
which ques
How to attach pictures... I've also answered such question
okk okk bt plzz ans me here if u dont have any prblm
Actually I can't attach a pic in comments so I told u to see that answer. I've shown a pic in it marking the symbol of a camera. If you are using the app then you can find the symbols just above your keyboard

If you are using website
no i am using app
Then you will see a symbol of a paperclip there. Click it

The material used in the filament of the bulb is Tungsten. It is used because a lot of electricity passes through the filament and a lot of heat is produced. The filament should have a night melting point to prevent it from melting down and breaking the circuit. Tungsten has a very high melting point ( 3422° C). Hence it is used for making the filament of the bulb.
