Class 12 Physics (India): Conductors insulators and semiconductors

Why do certain things behave like conductors while others don't? This may seem like a pretty simple question, but it's not. To really answer this question we need to dig deeper into the electron energy levels of a solid. In this video, we will use the band theory to figure out what makes certain things behave like conductors, insulators and semiconductors. 

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.

Band theory of solids

Why do some things conduct electricity readily while others don't? Turns out we need to learn a new theory of solids called 'band theory' to answer this question. In this section we will explore why we need this new theory, what is this band theory, and how we can use it to explain the conducting properties of solids.
