EEE :: D.C. Generators
- Equalizer rings are required in case armature is
- According to Fleming's right-hand rule for finding the direction of induced e.m.f., when middle finger points in the direction of induced e.m.f., forefinger will point in the direction of
- Following energized winding of a D.C. machine should not be opened as it would produce high inductive voltage which may be dangerous to personnel and may cause its own insulation failure.
- The essential condition for parallel operation of two D.C. generators is that they have
- A D.C. generator works on the principle of
- In a D.C. generator in case the resistance of the field winding is increased, then output voltage will
- In case of D.C. machines, mechanical losses are primary function of
- Which of the following generator will have negligible terminal voltage while running on no-load?
