Electrostatics: Gauss Theorem

This lecture covers the Gauss theorem in electrostatics, defining a closed surface enclosing a region in space and the concept of electric flux through a closed surface. It explains the relationship between electric field strength, area, and flux, and how the flux is proportional to the sum of charges inside the surface. The lecture also discusses cases where the flux enters or exits a closed surface, based on the direction of the electric field. Various examples and analogies are provided to illustrate these concepts.
