When two D.C. series generators are running in parallel, an equilizer bar is used________?
Ato increase the series flux
Bto reduce the combined effect of ar-mature reaction of both machines
Cso that two similar machines will pass approximately equal currents to the load
Dto increase the speed and hence generated e.m.f.
Correct answer
C. so that two similar machines will pass approximately equal currents to the load
Explanation
The correct answer is so that two similar machines will pass approximately equal currents to the load.
