Wire C and wire D are made from different materials and have length L_C = L_D = 1.9 m. The resistivity and diameter of wire C are 3.7 10^-6 ?m and 1.23 mm, and those of wire D are 2.7 10^-6 ?m and 0.68 mm. The wires are joined as shown in the figure and a current of 2.2 A is set up in them. What is the electric potential difference between (a) points 1 and 2 and (b) points 2 and 3? What is the rate at which energy is dissipated between (c) points 1 and 2 and (d) points 2 and 3?
