Apart from being an noble or inert gas it is one of the cheaper gases so therefore reduces the cost that is passed onto the customer.
Argon(or nitrogen) and tungsten are used in incandescent light bulbs.
I do believe it's Argon.
Nitrogen
inert gases ..like nitrogen or argon
Most incandescent light bulbs contain argon gas and a small amount of nitrogen. These gases help to prevent the filament from oxidizing and burning out too quickly. LED and fluorescent bulbs contain a mixture of gases like argon, xenon, and mercury vapor.
No, light bulbs are typically filled with either a vacuum (no air) or an inert gas like argon. Nitrogen is not commonly used in light bulbs because it does not provide the same level of protection for the filament as argon.
neon, argon, nitrogen are all possible answers.
Argon. As an inert gas, it makes the filament last longer. Some light bulbs also use Krypton.
The gas most commonly used in incandescent light bulbs is argon, which helps to prevent the filament from oxidizing and burning out too quickly. Other gases, such as nitrogen and krypton, may also be used in combination with argon to improve the efficiency and lifespan of the bulb.
Argon or dry nitrogen are common fill gasses in high wattage bulbs. But low wattage bulbs are just vacuum with no fill.
Argon and nitrogen are the two main gases used in bulbs today.See related links below
No, there is a vacuum or inert gas such as argon or nitrogen inside light bulbs to prevent oxidation and prolong the lifespan of the filament. Air does not play a role in the functioning of a light bulb.
