Two perfectly conducting cylindrical surfaces of length are located at = 3 and = 5
Question:
Two perfectly conducting cylindrical surfaces of length are located at ρ = 3 and ρ = 5 cm. The total current passing radially outward through the medium 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 σ = 0.05 S/m is present for 3 < ρ < 5 cm.
(b) Show that integrating the power dissipated per unit volume over the volume gives the total dissipated power.
