What does the bulb do on a light bulb?
It provides a protective, oxygen-free atmosphere for the filament, the glow wire. If the wire was to be heated in regular air, it'd burn and break immediately.
Why the electric bulb does not works if oxidation takes place inside it?
Because the filament will burn, and the filament is the part that produces the light.
In a bulb noble gas argon is used . why is argon is used instead of air in the light bulb?
It won't burn the filament.
How the bulb light?
An electrical current is passed through the high resistance filament in the bulb, causing it to become white hot and so give off light. The inside of the bulb is filled with an inert gas, such as nitrogen, so the filament does not burn up .

Why do they use argon gas in a light bulb?
It is used to replace oxygen so that the hot filament does not get oxidised or burn.
Why do bulb filament not burn?
The filament does not "burn", it just glows brightly. If some air were present in the bulb - as sometimes happens if a light bulb gets knocked and gets even a tiny crack in its glass bulb - then the oxygen present in ordinary air will quickly make the filament burn away.For more information see the answer to the Related question sghown below.
What will happen if a light bulb gets too much electricity?
If its an incandescent bulb the filament burns out; depending on the voltage put through the bulb (and the operating voltage of the bulb) the results can be quite spectacular. Normally the filament will burn out with a bright flash, if the voltage is high enough the bulb may explode.
Why bulb filament does not burn at high temperature?
The metal will melt if you do that.
Why would a light bulb burn out after two days of use?
If a light bulb is handled roughly before it was installed, the filament holder could have been weakened. Another reason that bulbs burn out before their time is that they are being submitted to a higher voltage than the bulb rated for.
Why do you use Argon in a light bulb instead of oxygen?
The current flowing through the filament causes it to heat to a very high temperature - so high that is becomes incandescent (glows) and gives light. If the bulb was filled with oxygen then, at those high temperatures, the filament would oxidise - burn out - and the bulb would be "blown".
Can a light bulb work with just oxygen instead of argon?
No. Light bulb filaments become extremely hot when in use, and oxygen, which is highly reactive, would cause the filament to burn away in a matter of seconds. Argon is used because it is inert, and thus will not react with the filament.
