How does a Light bulb work (in depth please)?
That really depends on the type of light. There is incandescent and fluorescent. Incandescent lights use a thin coiled coil of tungsten carbide (WC). Tungsten Carbide is used because it is very strong and has an extremely high melting point. It therefor lasts longer. So what happens is the electrons flow into it and through the filament. The filament is very thin, and has a higher resistance. So the electrons flowing will make the tungsten carbide molecules vibrate, generating heat. It is hot enough it generates the bright light and radiant heat. The glass is filled with nonreactive gases at low pressure to keep the filament from reacting and oxidizing, making it last longer. Fluorescent lights use mercury vapor in the tube. There are coiled tungsten carbide filaments at each end of the tube. The electrons are generated and released into the tube. When an electron collides with a mercury atom, the collision generates ultraviolet radiation. This shines on the phosphor coated glass, whic
