How does a forward biased diode work at the molecular level? - Part 2 | Intermediate Electronics

We've gone over the PN junction of a diode in a previous video and now we're talking about when it's forward biased! This is when things get serious - understanding a forwarded biased PN junction not only helps in understanding how a diode works but practically any semiconductor devices - transistors, thyristor, TRIAC, photocouplers, etc. We're laying the foundation for conceptually understanding how any current electronic device works with this. Once we go over the reverse biased junction, it should all come together! Subscribe to CircuitBread for more videos on intermediate electronics!
