The simplest light bulb is Thean contestant Light bulb, which has three basic parts the base filament and the glass bulb enclosure. The base connects the lightbulb to the power source that provides electrical voltage. The base also holds the contact wires, through which electricity must continuously flow to energize the filament. The filament is a part that heats up until it starts glowing to give off light. An incandescent light bulbs filament is made of tungsten, a periodic table metal with a very high melting point. This very high melting point allows tungsten to remain stable enough for the light bulb to continue working.
