An electric train runs between two sub- stations 6 km apart maintained at voltages 600 V and 590 V respectively and draws a constant current of 300 A while in motion. The track resistance of go and return path is 0.04 Q/km. Calculate : (i) the point along the track where minimum potential occurs (ii) the current supplied by the two sub- stations when the train is at the point of minimum potential.
