Question

difference between element of a bulb and filament of a bulb​

Answer 1

Element of a bulb

Irving Langmuir, an engineer working for General Electric, introduced the idea of filling the bulbs with a mixture of argon and nitrogen in 1908. These gases equalize vapor pressure inside and outside the bulb, and argon prevents the tungsten filament from wearing out. Modern bulbs contain mostly argon

filament of a bulb

The filament is the part of the light bulb that produces light. Filaments in incandescent light bulbs are made of tungsten. When electric current goes through the filament, the filament glows. ... To make the bulb produce more light, the filament is usually made of coils of fine wire, also known as the coiled coil.
