Structure of Incandescent Bulb Using 3D Model: Double-Coiled Filament | Connectors | Base | Foot

In this video Mayank explains the structure of an electric bulb. Inside a traditional bulb there is a very thin filament made of tungsten- filament has a high resistance and high melting point. The air inside the bulb is removed and filled with an inert gas like argon. The filament in a light bulb is made of a long, incredibly thin length of tungsten metal. In a typical 60-watt bulb, the tungsten filament is about 2 meters long but only one-hundredth of an inch thick. The tungsten is arranged in a double coil in order to fit it all in a small space. That is, the filament is wound up to make one coil, and then this coil is wound to make a larger coil. The base of electric bulb and metal tip at base are separated by an insulator CBSE: https://www.doorsteptutor.com/Exams/C... NTSE: https://www.doorsteptutor.com/Exams/N...
