The original electric light bulb has been in practical existence for around a century. It produces light through the passing of an electric current through a thin and fragile tungsten wire or filament, causing it to glow and emit light. This type of bulb is now generally categorized as an incandescent light after its primary cause of light emission. Most people refer to this as the electric light bulb and its creator or inventor as Thomas Edison.
