Neon gas has a break-down voltage of about 70 volts. When the gas (in a neon voltage regulator tube) breaks down, the gas glows red. If more voltage is applied (within sensible limits) the voltage drop across the neon VR tube will still be 70 volts. This action by itself could result in a large current flowing in the gas tube and possibly to destroy it, so a resistor is placed in series with the neon VR tube to limit the current. And this is better for the neon tube as well.
THUS a neon voltage regulator tube forms a reference voltage which can be used, with clever circuitry, to regulate any voltage.
Other gas mixtures are used for other voltages. There are solid-state devices with similar properties.

Do neon lights have gas?
Neon is one of the noble gases - helium, neon, argon, krypton, xenon. Gas discharge lights, commonly called neon lights, will produce different colors depending on which gas is used. Neon itself produces an orange light. The Wikipedia entry ' Noble Gas' has a nice illustration near the end showing the colors produced by each of the above gases
What is the common commercial uses to neon?
The common commercial use of the neon gas is to make bulbs. It is used because it is an inert gas. It does not react with the other elements.
Is neon a reactant?
No. Neon, as a noble gas, does not react with ANYTHING.
What is neons ductility?
Neon is a gas, and the concept of ductility applies to malleable solids. The 'melting point' of neon is about 25 Kelvin.
Neon does not exist as a diatomic molecule?
I dont think that Neon exists as a diatomic molecule, but I couldn't say for sure because the people on ask.com obviously don't know much about this. And neither does my chemistry book, or my mom.
What is the natural form of the element neon?
Usually a gas, neon is also available as a pressurized liquid. Neon gas is used in red lights used as exit signs or illuminated advertising signs, TV picture tubes, lasers, and voltage testers. Liquid neon is used as a refrigerant in cryogenics.
How is neon use?
Neon is used to make neon signs. Neon and helium are used to make gas lasers. Neon is used in lightning arrestors, television tubes, high-voltage indicators, and wave meter tubes. Liquid neon is used as a cryogenic refrigerant, as it has over 40 times the refrigerating capacity per unit volume than liquid helium and over three times that of liquid hydrogen.
How is neon used in today's world?
Neon gas is used in neon-signs, Vegas is full of them.
What gas is used in neon signs?
Neon
Does it have to be a noble gas in neon lights?
Neon lights are usually with neon or other inert gases at a low pressure, where when voltage gets through they shine.
Gas uses in lighted signs to produce a red color?
The gas used is neon.
What are 5 common uses of neon?
Uses of Neon :-Neon is used for lightings. : Neon discharges electricity, and produces bright lights. When mixed with other substances, various colours are produced inside tubes. Used in lamps, sign boards and lightingsInert Gas : Neon is an inert gas, and this property can be used for Cryogenic refrigerantUsed in vacuum tubes
What is a noble or inert gas used in street signs?
The answer to this is neon.
What are three uses for the element neon?
It is used in making neon advertising signs, which accounts for its largest use and slo to make high-voltage indicators, lightning arrestors, wave meter tubes, and TV tubes. Neon (and helium) are used in making gas lasers and liquid neon is an economical cryogenic refrigerant.
What are some uses for neon?
Neon is used in neon lights, which are gas discharge lamps that give off colored light. They have been widely used in advertising. Neon is used to make neon lasers and helium-neon gas lasers. It is also used as an inert gas (originally in vacuum tubes) and in processes such as cryogenic applications.
What is a gas used in advertising signs?
Neon
Why argon and neon gas used in sodium vapour lamp?
Neon and argon are used as a gas starter in sodium lamps.
