2. Potential Inside a Sphere We are interested in the electric potential inside a spherical shell that is radius a and centered on the origin. There are no charges inside the she, so the potential satisfies the Laplace equation, However, there is an external voltage applied to the surface of the shell which holds the potential on the surface to a value which depends on θ: As a result, the potential Ф(r,0) -by symmetry, it does not depend on ф-is...

How do you calculate the resistance through a thin spherical shell connecting a potential difference. Say on one end of a metallic balloon that is a perfect sphere is a 7200 volt wire and the other end is touching a ground. I just cant figure out how to calculate the resistance through the spherical shell (balloon). Do not give me the answer where you calculate current from inside to outside. In this case the current is flowing over the surface...
