Question

Which effect of current does the filament in electric bulb utilize​

Answer 1

The filament of an electric bulbconsists of tungsten with a high melting point. A filament is enclosed in a glass envelope which is filled with nitrogen and argon gas. 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
