Marshall Islands sphere capacitor capacitance derivation

Why does a single sphere have a capacitance?

This is because a single sphere is truly 3D while a plate is essentially 2D and a cable is 1D. The derivation of the capacitances for these shapes is inconsistent, as they assume different conditions. To compute the capacitance of an arbitrary conducting 3D shape, one needs to assume an outer shell and let it go to infinity.
