Two metal spherical shells of radius a and b share a common center (i.e. concentric shells). There is a material throughout the entire region between the shells of homogeneous conductivity o. (a) If the potential difference between the shells is V, determine the amount of current, I, that flows from one to the other. Hint: The electric field between the shells is Q (2) where Q is the charge on one of the shells. (b) Calculate the resistance, R, between the two shells.
