Electrical Engineering Basics - The Strange Discovery That Made Computers Possible

How Edison's abandoned discovery started electronics To learn for free on Brilliant 👉 http://brilliant.org/Theengineeringmindset Brilliant’s also given our viewers 20% off an annual Premium subscription, which gives you unlimited daily access to everything on Brilliant. Discover how Thomas Edison’s forgotten discovery sparked the creation of the vacuum diode, triode, and ultimately the transistor, the foundation of all modern electronics and the computer age. In this video, we explore the evolution of diodes, semiconductors, LEDs, rectifiers, and the atomic science behind PN junctions, showing how a simple effect inside a light bulb transformed into a multi-trillion-dollar industry. If you want to understand electronics, radio, silicon, germanium diodes, Zener diodes, Schottky diodes, LED technology, and the origins of modern computing, this is the perfect deep-dive.
