The Structure Of The Bulb
Nov 27, 2018

The structure of the bulb is very simple. It has two metal contact points at the bottom, which are used to connect electricity. A metal contact point has two lines touching a thin metal filament. The filament sits in the center of the bulb and is supported by a glass. Wire and filament are enclosed in a glass bulb filled with inert gas, usually argon. When the bulb is connected to the power supply, the current will flow from one contact point to another and then to the wire and filament.
