Electrical Engineering : Dc Generators QUESTIONS AND ANSWERS :: part4 : 6 to 10

Following Electrical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2024 and IES 2024 examinations :

6.In case of a flat compounded generator

voltage generated is less than the rated voltage
generated voltage is proportional to the load on the generator
voltage remains constant irrespec�tive of the load
speed varies in proportion to the load on the generator

7.In over compounded generator, full load terminal voltage is

almost zero
less than noload terminal voltage
more than noload terminal voltage
equal to no-load terminal voltage

8.A sinusoidal voltage of 5 Hz is applied to the field of a shunt generator. The armature voltage wave

will be zero
will be of 5 Hz
willbeof5xiVHz
will be of v Hz 5

9.When two D.C. series generators are running in parallel, an equilizer bar is used

to increase the speed and hence generated e.m.f.
to increase the series flux
so that two similar machines will pass approximately equal currents to the load
to reduce the combined effect of ar-mature reaction of both machines

10.Wave winding is composed of

any even number of conductors
any odd number of conductors
that even number which is exact multiple of poles + 2
that even number which is exact multiple of poles
