A 2-wire d.c. distributor A B is fed at both ends at the same voltage of 230 V. The length of the distributor is 500 metres and the loads are tapped off from the end A as shown below : Load : 100 A 60 A 40 A 100 A Distance : 50 m 150 m 250 m 400 m If the maximum voltage drop of 5-5 V is to be allowed, find the X-sectional area of each conductor and point of minimum potential. Specific resistance of conductor material may be taken as 1-73 × 10: [1-06 cm ; 250 m from A] Qm.
