2. A cylindrical conductor consisting of two different regions is given in the figure. In the cylinder, the
r< a region is filled with copper (o = 5.96 x 107 S/m) and the a <r <b region is filled with
aluminum (o = 3.5 × 107 S/m). The cylinder is positioned between z = 0 and z = L. A DC voltage V
is applied between the ends of the cylinder. The electric field intensity is given as
V
E = 2-
between the ends of the cylinder. (a = 2 mm, b = 4 mm, L = 1 km and V = 10 V)
(20 points) Calculate the resistance of the wire.
