TUTORIAL PROBLEMS 1. A 2-wire d.c. distributor AB, 1000 m long has a total resistance of 0-1 2. 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: (1) the point of minimum potential (i) value of minimum potential (iii) current fed at both ends [() 400 m from A (i) 231-76 V (iii) I = 366 A ; Ig = 454 A]
