Question
A 2-wire d.c. street mains AB, 600m long is fed from both ends at 220 V, Loads of 20A, 40A, 50A and 30A are tapped at distances of 100m, 250m, 400m and 500 m from the end A respectively. If the area of X-section of distributor conductor is $1\text{ cm}^2$, find the minimum consumer voltage. Take $\rho = 1.7 \times 10^{-6}\ \Omega\text{ cm}$.
