Wire C and wire D are made from different materials and have length Lc = LD = 1.0 m. The resistivity and diameter of wire C are 2.0 x 10-6 ?? ?? m and 1.00 mm, and those of wire D are 1.0 x 10-6 ?? ?? m and 0.50 mm. The wires are joined as shown in Figure and a current of 2.0 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?
