1. The problem statement, all variables and given/known data Find the electric field between the conductor and ground. The conductor is at: Potential = +V0, radius a distance d from the ground plane. 2. Relevant equations I used image theory to create a conductor at -V0 at distance -d from the ground plane. Laplace's equation: ∇2V = 0 3. The attempt at a solution My main road block on this problem is that the cylindrical conductor is NOT at the origin. This means the symmetry in φ and z do not apply, and I cannot easily solve Laplace's equation since V = V(r,φ,z) instead of V = V(r) for a cylinder at the origin. Note that I am in second year electrical engineering, so I don't think we are supposed to solve PDEs... Also, if I set my positive charged conductor at the origin, then my image conductor is still not symmetric with respect to φ and z, and I face the same concern. Can someone give me a hint on what to do when the conductor is not centered at the origin? Right now, I have the ground plane set as the y = 0 plane and the conductor lying on x = 0. Thanks a lot!!
