To provide sufficient resistance to electrons so that heat produced will cause thermionic emission.
The filament becomes hot when electricity passes through it, due to resistance in the wire. This resistance causes the filament to heat up and emit light in an incandescent bulb.
The hot filament in an incandescent light bulb is protected by a glass bulb filled with an inert gas, such as argon or nitrogen. This gas prevents the filament from reacting with oxygen in the air, allowing it to glow and produce light.
Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.
The filament will emit a white light when the switch is turned on.
A light bulb is created when a filament becomes so hot that it glows. The high temperature causes the metal filament to emit light, which produces illumination in the bulb.

A filament is part of a bulb.I will give you a full sentence. "The filament of a bulb is the part that gets hot and produces light"
The filament or element gets hot and passes it's heat into the water.
Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.
The filament will emit a white light when the switch is turned on.
incandescent lights
When a current is passed through a thin wire filament it gets hot. Insulate the filament in a glass envelope with no air, and the filament glows brightly.
A light bulb is created when a filament becomes so hot that it glows. The high temperature causes the metal filament to emit light, which produces illumination in the bulb.
An electric lamp, also known as a light bulb, functions by using electricity to heat a thin filament inside a glass bulb. As the filament heats up, it produces light. The bulb is filled with an inert gas to prevent the filament from oxidizing and burning out quickly. When the electricity flows through the filament, it causes the electrons to jump and emit photons, creating light.
