EEE :: D.C. Generators
- A cumulatively compounded long shunt generator when operating as a motor would be
- If brushes of a D.C. generator are moved in order to bring these brushes in magnetic neutral axis, there will be
- Two D.C. shunt generators, each with armature resistance of 0.02 ohm and field resistance of 50 ohm run in parallel and supply a total current of 1000 amperes to the load circuit. If their e.m.fs. are 270 V and 265 V, their bus bar voltage will be
- Which of the following generators will be preferred if they are required to be run in parallel?
- In a D.C. generator the critical resistance can be increased by
- In a D.C. machine, short-circuited field coil will result in
- Eddy currents are induced in the pole shoes of a D.C. machine due to
- The demagnetizing component of armature reaction in a D.C. generator
