Question

name the substance which is use to make bulb filament.

Answer 1

Before LEDs, and before CFLs, we used Tungsten Filament Lamps, you might still find these in some legacy applications but they are banned in most countries. As is pretty obvious, the filament in a Tungsten Filament Lamp is made from Tungsten. Tungsten is used because it has a high melting point (3,695K)

Answer 2

Tungsten is used to make bulb filaments.It is used in making bulb filaments as it has a melting point of around 3000℃
