Answer:
Filaments in incandescent light bulbs are made of tungsten. When electric current goes through the filament, the filament glows. It may also be known as the electron emitting element in a vacuum tube. To make the bulb produce more light, the filament is usually made of coils of fine wire, also known as the coiled coil and it has a melting point of 3380C
