WebTungsten is an element that gets very little attention in day-to-day life, but this important element is used for everything from the household incandescent light bulb to radiation … WebJul 7, 2024 · How does a light bulb work simple? The incandescent light bulb turns electricity into light by sending the electric current through a thin wire called a filament. Electrical filaments are made up mostly of tungsten metal. The resistance of the filament heats the bulb. Eventually the filament gets so hot that it glows, producing light.
