2. A DC distributor cable AB is fed at its ends A and B. Loads of 48A, 72A, 24A and 12A are taken from the cable at points C, D, E and F. The resistance of sections AC, CD, DE, EF and FB of the cables are 8, 6,4,10 and 5 m2 respectively (for the go and return conductors together). The voltage at points A & F is 240V. Estimate: i. the voltages at the feeding point B, the current supplied by each feeder ii. the potential differences at the loads C,D and E.
