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 |
