DC Distribution
Question 39 In DC network A is the feeding point and is maintained at 250 volt . the resistance of the various branches (go and return) are indicate in the figure . determine the current in each point per branch ? Question 31 A 2 wire DC distributor AB is 300 meters long . the end A is fed at 205 volt and end B at 200 volt . the distributor is uniformly loaded at 0.15 ampere per metre length and has connected load of 50 ampere , 60 ampere , and 40 ampere at points distance 75 , 175 , 225 meter respectively from the end A .the resistance of each conductor is 0.15 ohm per kilometre . calculate (1) the point of minimum potential , (2) currents fed at end A and B . Question 32 A DC 2 wire distributor AB is 450 meter long and is fed at both ends at 250 volt . The distributor is loaded as diagram. The resistance of each conductor is 0.05 ohm per kilometre. Find the point of minimum potential and its p...
