Question

A 2-wire DC distributor AB of length 500 m is fed at both ends with equal voltage of 250 V. Loads of 50A, 60 A, 40 A and 30 A are tapped at distance of 100 m, 250 m, 350 m and 400 m from end A respectively.
If the cross-section area of each conductor is 1 cm2 and the resistivity of the material of the conductor is 1·7 μΩcm,

1) Calculate the overall efficiency of the network
