What’s REALLY Inside an Incandescent Light Bulb

Описание: Description:

Most of us use incandescent light bulbs every day… but almost nobody actually knows what’s going on inside them.
In this video, I break down how an incandescent bulb is made, what components are inside it, and how it really produces light. From the thin tungsten filament to the glass envelope and inert gas inside, we take a simple-looking bulb and expose the physics and engineering behind it.

I also explain why incandescent bulbs get so hot, why they glow instead of sparking, and why so much energy is lost as heat. Once you understand this, you’ll never look at a light bulb the same way again.
This video is meant to be simple, visual, and educational, whether you’re just curious about electronics or you’re learning physics and electrical engineering basics.
