A 3-wire DC distributor 400 m long is fed at both ends at 235 volts between each outer and neutral. Two loads P and Q are connected between the positive and neutral and two loads R and S are connected between the negative outer and the neutral. The loads and their distances from one end (M) of the distributor are as follows: Load P, 51 A, 100 m from M; Load Q, 74 A, 300 m from M; Load R, 60 A, 150 m from M; Load S, 64 A, 350 m from M. Determine the p.d at each load point and the current at each feeding point. The resistance of each outer is 0.25 0 per 1000 m and that of the neutral is 0.5 Q per 1000 m.
