DC Generators In D.C. generators the polarity of the interpoles Is neutral as these poles do not play part in generating e.m.f. Is the same as that of the immediately preceding pole Is the same as that of the main pole ahead Is opposite to that of the main pole ahead Is neutral as these poles do not play part in generating e.m.f. Is the same as that of the immediately preceding pole Is the same as that of the main pole ahead Is opposite to that of the main pole ahead ANSWER DOWNLOAD EXAMIANS APP

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