Two perfectly conducting cylindrical surfaces are located at p= 3 and p= 5 cm. The total current passing radially outward through the med- ium between the cylinders is 3 A dc. (a) Find the voltage and resistance between the cylinders, and E in the region between the cylinders, if a conducting material having o = 0.05 S/m is present for 3 < p< 5 cm. (b) Show that integrating the power dissipated per unit volume over the volume gives the total dissipated power.
