EM fields lecture 18 - electric potential of charged sphere & charged disk and choosing V=0
A charged sphere and disk reveal how superposition derives potential and how the choice of V = 0 depends on whether charge is finite or infinite.
EM fields lecture 19 - field, potential & charge densities of conductor in electric fields
At electrostatic equilibrium, a conductor is equipotential with zero interior field, and its surface charge determines the normal external field.
