A 2-wire d.c. distributor AB, 1000 m long has a total resistance of 0·1 Ω. The ends A and B are fed at 240 V. The distributor is uniformly loaded at 0.5 A/metre length and has concentrated loads of 120 A, 60 A, 100 A and 40 A at points distant 200, 400, 700 and 900 m respectively from end A. Calculate: (i) the point of minimum potential (ii) value of minimum potential (iii) current fed at both ends
