Where natural light is insufficient.
Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.
Usually the light bulbs used are resistive components, but the energy savers used now a days are inductive components and they are used because they consume reactive(inductive) less useful power and save useful or real (resistive) power.
They're made of Tungsten.
Domestic light bulbs are simply the light bulbs (usually of the filament type) used in the home.
There are several such as Tungsten a metal used in electric bulbs.
Electric bulbs are typically filled with inert gases such as argon, krypton, or xenon. These gases help prevent oxidation of the filament inside the bulb, allowing it to glow brightly without burning out quickly.
Usually tungsten.
No, hydrogen is not typically used to fill light bulbs. Light bulbs are usually filled with inert gases like nitrogen or argon to prevent oxidation of the filament, which would reduce the bulb's lifespan.
Electric bulbs do have the inert gasses inside and not oxygen to avoid explosions.
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.
Electric bulbs are typically filled with inert gases such as argon or nitrogen. These gases help to prevent the tungsten filament from oxidizing and burning out quickly, thus extending the bulb's lifespan. In some cases, a small amount of other gases, like krypton or xenon, may also be used to improve efficiency and brightness.
