Electrodynamics lessons

Simple explanation of the Maxwell's equations for beginners. The divergence integral and the curl integral theorems are also explained.

Here you will learn how an electrical circuit works and how to apply Ohm's Law to it. You will also learn about parallel and series circuits and their difference.

List of important physical quantities, their symbols, (derived) units and examples with images.

Learn about important physical constants and what their formula symbols and SI units are.

Here you will learnthe wave equations for the E-field and B-field of an electromagnetic wave and how it can be simplified to a plane wave.

Here you will learn about polarized light, i.e. linearly or circularly polarized electromagnetic waves, and what characterizes them.

You learn how to use the hand rule to determine the direction of the Lorentz force and whether you have to use your right or left hand.

Explanation of what the Hall effect is, how exactly the Hall voltage is generated and how you can calculate it and the Hall constant.

Learn how Lorentz force (magnetic force) deflects a moving charge (electron) in the magnetic field and how you can determine the direction of the deflection.

Here you learn Ohm's law, how it is expressed as a formula and as a graph. We also look at three examples.
