please answer the questions below

Wire C and wire D are made from different materials and have length Lc= Lp = 3.6 m. The resistivity and diameter of wire C are 4.0 x 106 O.m and 1.04 mm, and those of wire D are 2.9 x 10 0.m and 0.82 mm. The wires are joined as shown in the figure and a current of 2.4 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 -C LD 2 (a) Number HI Units V [b) Number HI Units (c) Number Units (d) Number Units
