Unformatted text preview: What is the current in the silver section? (c) What is the magnitude of E in the copper? (d) What is the magnitude of E in the silver? (e) What is the potential difference between the ends of the silver section of wire? 25.66 The region between two concentric conducting spheres with radii a and b is filled with a conducting material with resistivity . (a) Show that the resistance of the spheres is given by: (b) Derive the expression for the current density as a function of the radius, in terms of the potential difference V ab between the spheres. (c) Show that the result in part (a) reduces to: when the separation between the spheres L=b-a is small....
