Figure A shows two concentric metal spherical shells separated by a weakly conducting material of conductivity (o ). The inner shell has a radius of (a, = a), and the outer shell %3D has a radius of (a, =3.5a ). Assume the inner shell carries a charge (Q), and the two shells %3D are maintained at a potential difference (V). Find: 1- The current (I) flowing from one shell to the other? 2- The resistance between the shells (R)?
