Class 12 Physics (India): Forward and reverse current mechanism

What's the mechanism of charge flow in forward and reverse bias? In this video, let's go deeper and explore the mechanism of the current in both forward and reverse bias. We will see that's way different than what happens inside a conductor. 

Class 12 Physics (India)

It is now time to dive deeper into the world of physics with topics from class 12 (NCERT) such as electrostatics, electricity, magnetism, electromagnetic induction, and electromagnetic waves. Let's also learn more about light with ray optics and wave optics. Finally, let's look at what happened in the last hundred years of physics by getting introduced to quantum mechanics with dual nature of radiation and matter, atoms, nuclei, and semiconductors.

PN junction biasing

Building a one-way valve. The key to making a computing device is to be able to build a one-way valve (something that only allows a flow of charges in 1 direction) with no moving parts. In this section, we will explore how the PN junction act's as a one-way valve.
