Electrical Engineering : Dc Generators QUESTIONS AND ANSWERS :: part3 : 1 to 5
Following Electrical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2024 and IES 2024 examinations :
1.If a D.C. generator fails to build up the probable cause could not be |
| imperfect brush contact |
| field resistance less than the critical resistance |
| no residual magnetism in the generator |
| faulty shunt connections tending to reduce the residual magnetism |
2.Permeance is the reciprocal of |
| flux density |
| reluctance |
| ampere-turns |
| resistance |
3.In a D.C. generator the number of mechanical degrees and electrical degrees will be the same when |
| r.p.m. is more than 300 |
| r.p.m. is less than 300 |
| number of poles is 4 |
| number of poles is 2 |
4.The purpose of providing dummy coils in a generator is |
| to reduce eddy current losses |
| to enhance flux density |
| to amplify voltage |
| to provide mechanical balance for the rotor |
5.In a D.C. generator the magnetic neutral axis coincides with the geometrical neutral axis, when |
| there is no load on|he generator |
| the generator runs on full load |
| the generator runs on overload |
| the generator runs on designed speed |
