I am currently studying "Principles of Power System by V. K. Mehta". I am stuck at a tutorial problem from chapter 13, which is as follows:
A 2-wire d.c. distributor, 500 m long is fed at one of its ends. The cross-sectional area of each conductor is 3·4 cm² and the resistivity of copper is 1·7 μΩcm. The distributor supplies 200 A at a distance of 300m from the feeding point and 100 A at the terminus. Calculate the voltage at the feeding end if the voltage at the terminus is to be 230 V.
Here is my solution:
