Short note on electric bulb.
Answers
The incandescent light bulb turns electricity into light by sending the electric current through a thin wire called a filament. Electrical filaments are made up mostly of tungsten metal. The resistance of the filament heats the bulb. Eventually the filament gets so hot that it glows, producing light.
The filament is the part of the light bulb that produces light. Filaments in incandescent light bulbs are made of tungsten. Whenever an electric current goes through the filament, the filament glows. ... To make the bulb produce more light, the filament is usually made of coils of fine wire, also known as the coiled coil.
Incandescent light bulbs consist of an air-tight glass enclosure (the envelope, or bulb) with a filament of tungsten wire inside the bulb, through which an electric current is passed. Contact wires and a base with two (or more) conductors provide electrical connections to the filament
