Details: When the incandescent light bulb was invented, it changed the lives of people all over the world. The simple electrical device contains a tungsten filament which heats up and glows as it resists the flow of electricity passing through it. A sealed glass bulb, which contains no oxygen, encloses this fine wire to prevent it from burning up. Most indoor lamps and residential light fixtures use incandescent bulbs.
