DC Generators When two D.C. generators are running in parallel an equalizer bar is used To increase the generated e.m.f. To increase the series flux So that the two identical machines will pass approximately equal currents to the load To reduce the combined effect of armature reaction of both the machines To increase the generated e.m.f. To increase the series flux So that the two identical machines will pass approximately equal currents to the load To reduce the combined effect of armature reaction of both the machines ANSWER DOWNLOAD EXAMIANS APP
