Hey dude,
Electric bulb
❦Since the resistance of thin filament is very high, amount of heat production is large same as the electric current that flows through the filament.
❦Due to a large amount of heat production, the filament bulb becomes white hot.
❦Hence filament of bulb emits light and heat.

HERE'S YOUR ANSWER MATE:
In an electric bulb, there is a filament of metal such as tungsten having high melting point (3410°C).
When an electric current is passed through the filament, it becomes hot and emit light.
The bulbs are usually filled with chemically inactive gases such as nitrogen and argon to prevent oxidation of the filament and hence prolong their life.
Hope it helps you.
