Lecture
This lecture covers the concept of capacitance in electrostatics, starting with the definition of self-capacity and Gauss's law. It then explores the capacitance of single-conductor and two-conductor capacitors, including parallel plate capacitors. Examples of calculating the capacity of different geometries, such as conductive spheres and discs, are provided. The lecture also introduces the concept of mutual capacity and discusses the capacitance of capacitors with parallel plates and spherical conductors.
