Is a light bulb a source of light?

How does a light bulb turn electricity into light?

Incandescent light bulbs are devices that convert electricity into light by heating a filament, using electric current, until it emits electromagnetic radiation. As current passes through the filament, its high resistance causes its temperature to rise until it glows.

What is the power source of a lightbulb?

The incandescent light bulb consists of a thin tungsten filament inside of an inert gas-filled glass bulb. When electricity is applied across the filament, electrons begin to flow. These electrons encounter resistance from the tungsten material, and in turn produce energy as they collide. This energy turns into heat.

How does a electric bulb work?
