Domestic light bulbs are simply the light bulbs (usually of the filament type) used in the home.
Tungsten
Usually tungsten.
Tungsten is typically used as the filament in incandescent light bulbs because of its high melting point and ability to emit light efficiently when heated by an electric current.
Iron filaments are not used in light bulbs because they have a relatively high melting point and poor conductivity compared to tungsten, the metal commonly used in filament bulbs. Iron would not produce as much light or last as long as tungsten in a filament bulb.
Tungsten is an element. It is used in bulbs
Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.
parallel
Generally, tungsten.
Argon is used in filament light bulbs to displace oxygen and prevent the filament from burning. It creates an inert atmosphere inside the bulb, helping to prolong the life of the filament and improve the overall efficiency of the bulb.
Yes, argon is commonly used in incandescent light bulbs. It is often used to fill the space around the filament inside the bulb, helping to prevent oxidation and prolong the life of the filament.
Light is not used in light bulbs; light is created in light bulbs. From Edison to the invention of solid state devices, light bulbs were mostly incandescent. They made light by running electricity through a tungsten filament inside a glass bulb with the air removed. The filament got very very hot and emitted light waves (photons). The lack of air (oxygen) preserved the filament from burning up. The efficiency was atrocious, but they made light.
