What's inside a Incandescent light

On previous post, we learn about types of light bulb and their connection. Now we going to learn what inside a incandescent light bulb. This is a basic for every light bulb that revolutionize till today.Lets see what inside a Incandescent Light bulb.

 1) Glass bulb : protect the inner components and block infrared or Ultra violet light. It's made from Quatz glass

2) Tungsten filament : This is the filament that produce heat and light. It's has more reisistance because it's thin.

3) Contact Wire : This contact wire that connect to live and neutral that complete one loop to light up the bulb.

4) Stem : Not the plant stem :P It's a glass mold that holds the contact wire and supports wire.

5) Support wire : This will support the tungsten filament. If the filament is not in fixed place or fall off. The bulb will not light up. NO MORE LIGHT BUY NEW BULB :'(

How it's Works
 
When the light bulb is power up the contact wire that hold tungsten filament is heated and produce light. When it's heated and produce light,gas like argon,xenon,krypton are bounce right back toward the filament, where it will rejoin the solid structure. Since inert gases normally don't react with other elements, there is no chance of the elements combining in a combustion reaction.
