A two wire DC distributor AB, 1000 meter long, is supplied from both ends, 240 V at A and 242 V
at B. There is a concentrated load of 200 A at a distance of 400 meter from A and a uniformly load 1.0
A/m between the midpoint and end B. Determine (i) the current fed at points A and B (ii) the point of
minimum potential and (iii) voltage and this point. Consider cable resistance as 0.005 ohm per 1000
meter each core.
