Question
A d.c. distributor AB is fed at both ends. At feeding point A, the
voltage is maintained at 235 V and at B at 236 V. The total length of
the distributor is 200 meters and loads are tapped off as under:
20 A at 50 m from A
40 A at 75 m from A
25 A at 100 m from A
30 A at 150 m from A. The resistance per kilometer of one conductor
is 0.4 2. Calculate the minimum voltage and the point at which it
occurs.
