Wire C and wire D are made from different materials and have length Lc = Lo = 2.4 m. The resistivity and diameter of wire Care 4.4 x 10" (.m and 1.11 mm, and those of wire D are 1.2 x 10 0-m and 0.67 mm. The wires are joined as shown in the figure and a current of 2.1 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? C D 2 (a) Number i Units (b) Number Units (c) Number i Units V (d) Number Units
