How Incandescent Light Bulbs Work | Science & History Explained #4715 (License: Personal Use)

This illustration depicts a standard incandescent light bulb, featuring a coiled tungsten filament that emits light when heated by electric current. The glass bulb is filled with inert gas to prevent oxidation, and the threaded metal base allows secure installation into standard sockets. Though largely phased out for energy efficiency, it remains iconic in science education and design history.
