There are two concentric metallic spherical shells of radii a and b such that a b An ideal cell of emf is connected across the two shells The medium between the shells is filled with a dielectric of dielectric constant K and resistivity p For a point P at a distance from the common centre C where a r b A current density is B electric field is 2 ab pr b a ab r b a C current density is ab pr b a DI net current supplied by the cell is 4 ab
