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

11.The e.m.f. generated by a shunt wound D.C. generator isE. Now while pole flux remains constant, if the speed of the generator is doubled, the e.m.f. generated will be

E/2
2E
slightly less than E
E

12.In D.C. generators, lap winding is used for

high voltage, high current
low voltage, high current
