1. A 2-wire d.c. distributor AB is 300meters long. It is fed at point A. The various Loads and their positions are given below: At point C D E distance from A in meters 40 100 150 250 concentrated load in A 30 40 100 50 F If the permissible voltage drop is not to exceed 10V, find the cross sectional area of the distributor. Take resistivity =1.78 10-8 m
