Q6. A. Describe the materials used as conductors in cables; Conductor as the name suggest should be able to conduct electricity with negligible resistance. A section of a supply cable AB 1km long has a fault to earth such that, when end B is disconnected, the resistance measurement form end A to earth is 5 ohms. When end, A is disconnected, the resistance reading from end B to earth is 3 ohms. The length of the cable AB has a resistance reading from end B to earth is 3 ohms. The length of the cable AB has a resistance of 4 ohms when intact. Find the distance of the fault from end A.
