A TUTORIAL PROBLEMS 1. A 2-wire d.c. distributor AB 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: 0-03 aintained at notion. The Load: Distance: of minimum V and sub- 100 A 50 m 60 A 150 m 40 A 250 m 100 A 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 x 10 2 m. [1-06 cm; 250 m from A] 2. A d.c. distributor AB is fed at both ends. At feeding point A. the voltage is maintained at 235 Y
