How does the incandescent light bulb work?
A light bulb has a basic, simple structure to them. The base consists of a pair of metal contacts that connect to an electrical circuit. These contacts are attached to two separate stiff wires and these two wires are attached to a thin metal called a filament. This filament sits in the center of the bulb and is held up by something called a glass mount. These wires and the filament rest inside the glass bulb and is filled with either argon or other inert gasses.
