How an Incandescent Light Bulb Works - Explained with Diagram #2120140 (License: Personal Use)

This educational illustration shows a cutaway view of a standard incandescent light bulb, featuring a coiled tungsten filament suspended by two support wires (green and blue), connected to the metal base’s electrical contacts. The glass envelope is filled with inert gas to prevent oxidation, and the filament glows when current flows, producing light via incandescence. The diagram clarifies the path of electricity from the screw base through the leads to the filament.
