A light bulb is a device that produces light from electricity. Light bulbs turn the electricity to light by sending current through a thin wire called filament. The filament is usually made of tungsten, a material that emits light when electricity is passed through it. The emission of light is due to the high resistance offered by the material tungsten, which we will learn in higher classes.
