A power transmission line carries current from a 6000-V generator to three loads, A, B, and C. The loads are located at 4, 7, and 10 km from the generator and draw 50, 30, and 100 A, respectively. The resistance of the line is 0.1 Ω/km; see Fig. 3-21. 

(a) Find the voltage at loads A, B, C. 

(b) Find the maximum percentage voltage drop from the generator to a load.
