Electrodynamics - Finding the Potential Inside a Rubber Coated Charged Sphere

Learn to calculate the electric potential at the center of a charged metal sphere surrounded by a dielectric coating in this 18-minute physics tutorial. Work through the problem of finding the potential relative to infinity for a metal sphere of radius a carrying charge Q, which is surrounded by linear dielectric material with permittivity epsilon extending to radius b. Apply principles of electrostatics and boundary conditions to solve this classic electrodynamics problem involving dielectric materials and their effects on electric fields and potentials.
