At 20^oC the insulation resistance of a cable 500 meters in length is 480 M ? and the copper conductor resistance of the cable is 0.7 ?. If the insulating material has its resistance halved by a temperature rise of 10^oC, find per km length of the cable at 36^oC.

(i) Insulation resistance (ii) the resistance of copper conductor

Temperature coefficient of copper at 20^oC = 01.0043 per ^oC.
