You have seen that the excess charge on an isolated conductor moves entirely to the conductor’s surface. However, unless the conductor is spherical, the charge does not distribute itself uniformly. Put another way, the surface charge density s (charge per unit area) varies over the surface of any nonspherical conductor.
Why wouldn't the charge always distribute uniformly? I thought the charges would always want to maximize distance between themselves and so would spread out all over the conductor uniformly.
