DC Distribution
Question 47 A 3 wire DC distribution 250 m long is supplied at end P at 500/ 250 volt and is loaded as under . positive side : 20 ampere 150 m from P , 30 ampere 250 m from p , negative side 24 ampere from P , 36 ampere 220 m from p , the resistance of each outer wire is 0.02 Ohm per 100 meter and the cross- section of the middle wire is one half that of the outer . find the voltage across each load point . 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 5...
