What is the gas filled in light bulb?
Depends which kind of lightbulb. Incandescent light bulbs are not filled with gas. Energy saving lightbulbs may be filled with a range of gases. These include Neon, Phosphorus and Fluorine.
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".
Is a light bulb filled with Nitrogen?
yes and other gasses
Why is the inside of he bulb containing the magnesium is filled with a ''noble'' gas instead of air?
It might be metals or nonmetals in the bulb
What items contain tungsten?
Electric bulb Filament
Does an electric light bulb have oxygen?
no
Why is a filament light bulb not filled with oxygen?
because oxygen is not an inert gas
The gas usually filled in the electric bulb is?
Electric light bulbs are commonly filled with argon gas. The other ones could also be either helium, neon, nitrogen or krypton.
Why is there hardly any air in a glass bulb?
Hi! This is the question for this question! Because air was contained with oxygen and oxygen so oxygen with smallest heat it burns down the filament! This is also evacuated and filled with a gas which does not react with the red hot filament. So .... if air present the filament would quickly oxidise and fail to light up!
Why are electric bulbs filled with argon and nitrogen?
cuz it slows down the evaporation of d filament of the bulb....so that d bulb doesn't stop working.
Will an electric bulb glow when it is filled with vacuum instead of an inert gas like argon or nitrogen?
"filled with nothing" ??? yes is the answer your looking for, but the bulbs we use today are optimized to work with whatever gases each company uses. Oxygen is the destroyer of fillaments (remember the old flash bulbs?)
How are light bulbs made?
A light bulb is a high resistance wire surrounded by the bulb filled with an inert gas. When electric conducts through the wire, energy is lose as heat and light.
When the two bulb are in place what happen why?
Plant bulbs or electric light bulbs? More information is needed.
How does a dry cell make a lightbulb light?
When electric current flows through filament of the bulb, the electrons are squased among themselves due to the thin structure of the bulb. This causes them to emit light. Due to the gases filled in the light bulb, the bulb glows.
What is the gas filled in light bulb?
Depends which kind of lightbulb. Incandescent light bulbs are not filled with gas. Energy saving lightbulbs may be filled with a range of gases. These include Neon, Phosphorus and Fluorine.
Which gas is in electric bulb?
Modern bulbs are usually filled with a mixture of argon and nitrogen. More rarely, some bulbs are filled with pure argon, krypton or xenon. The earliest bulbs weren't filled with any gas, but had vacuum inside.
What is a electric bulb in short?
a bulb is light bulb
