In this video lecture on electrodynamics, we will be discussing the spherical polar coordinate system (r, θ, φ). This coordinate system is commonly used to describe three-dimensional space and is particularly useful in problems with spherical symmetry. We will cover the basic definitions of the spherical polar coordinates, how to convert between rectangular and spherical coordinates, and the applications of the spherical polar coordinates in electromagnetism.
