. By connecting the two (2) batteries of 1.5V in parallel, to total emf would be? . If two (2) generators are connected in parallel, their emf is equal to?

A d.c. serier generator, having an external characteristic which is a straight line through zero to 50 V 200 A is connected as a booster between a station bus bar and a feeder of 0.3 ohm resistane. Calculate the voltage difference between the station bus-bar and the far end of the feeder qa current of (i) 200 A and (ii) 50 A.
