Electric bulb

An electric bulb is a device that produces light by converting electrical energy into visible light. It consists of a glass bulb containing a filament made of tungsten, which is heated to a high temperature when an electric current passes through it. The filament emits light due to its high temperature, illuminating the surroundings. The bulb is typically enclosed in a base that allows it to be connected to an electrical circuit. Electric bulbs are commonly used in homes, offices, and various other settings to provide artificial lighting. They come in different shapes and sizes, including incandescent bulbs, fluorescent bulbs, and LED bulbs, each offering different levels of energy efficiency and lifespan.
