Wire C and wire D are made from di'l'fere nt materials and have length LC = Lg = 3.? m. The resistivity and diameter of wire C are 3.9 3-: iii)\"5 -m and 1.12 mm, and those of wire D are 2.2 x 10'6 -m and 0.68 mm. The wires are joined as shown in the gure and a current of 3.5 A is set up in them. What is the electric potential difference between {a} points 1 and 2 and lib} points 2 and 3? What is the rate at which energy:r is dissipated between [(2] points 1 and 2 and [d] points 2 and 3
