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 |
