Electrodynamics

The exercise teaches you how to calculate the charge of a thundercloud using the capacitance and E-field in the plate capacitor.

In this exercise (with solution) you have to calculate the distance between the capacitor plates for a given capacitance and and than use relative permittivity.

Derive the self-inductance and magnetic flux of two parallel current carrying conductors with opposite currents.

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

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.

In this video you will learn the basics of the electric current, i.e. the definition, its physical meaning and unit.⠀
