Wire C and wire D are made from different materials and have length Lc = Lp = 1.5 m. The resistivity and diameter of wire Care 4.9 x 10-6 2-m and 1.10 mm, and those of wire D are 3.8 x 1060-m and 0.62 mm. The wires are joined as shown in the figure and a current of 3.1 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?
