DC Generators The open circuit voltage of a compound generator is 250 V. At full load the terminal voltage May be greater or less than 250 V None of these Will be less than 250 V Will always be 250 V May be greater or less than 250 V None of these Will be less than 250 V Will always be 250 V ANSWER DOWNLOAD EXAMIANS APP
DC Generators When two D.C. generators are running in parallel an equalizer bar is used To increase the series flux To increase the generated e.m.f. 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 series flux To increase the generated e.m.f. 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
DC Generators The terminal voltage of a series generator is 150 V when the load current is 5 A. If the load current is increased to 10 A, the terminal voltage will be 150 V None of these Greater than 150 V Less than 150 V 150 V None of these Greater than 150 V Less than 150 V ANSWER DOWNLOAD EXAMIANS APP
