Electric bulbs work by passing an electric current through a filament, which heats up and produces light. The filament is typically made of tungsten, which has a high melting point. The light produced is a result of the filament glowing as it reaches high temperatures.

What is a filament that glows white hot in electric light bulbs?
Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.
How many light bulbs were in use at 1902?
It is difficult to determine the exact number of light bulbs in use in 1902 as there is no comprehensive record. However, it is estimated that the number of electric light bulbs in use around the world at that time was in the millions, as electric lighting was becoming more popular.
Why bulbs light?
Bulbs light up when an electric current passes through the filament, which heats up and emits light. This process is called incandescence.
Why argon is filled in electric bulbs?
Argon is filled in electric bulbs to prevent the filament from burning out quickly. It helps to reduce the evaporation of the filament, prolonging the lifespan of the bulb. Argon also improves the efficiency of the bulb by creating a stable environment for the filament to glow.
What is the filament that glows white hot in electric light bulbs?
The filament that glows white hot in electric light bulbs is typically made of tungsten. Tungsten has a high melting point and is able to withstand the high temperatures produced when an electric current passes through it, creating the desired white light.
Why electric bulbs don't have air inside?
Electric bulbs do have the inert gasses inside and not oxygen to avoid explosions.
What is a filament that glows white hot in electric light bulbs?
Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.
