Question
When the plane of the armature of an AC generator is parallel to the field, in which is it rotating?
- Flux linked is maximum while induced emf is zero
- The flux linked with it is zero, while induced emf is maximum
- Both the flux linked and induced emf in the coil are zero.
- Both the flux and emf have their respective maximum values
Hint:
The flux linkage becomes zero and the emf will be maximum when the coil is parallel to the magnet.
The correct answer is: The flux linked with it is zero, while induced emf is maximum
When the plane of the armature of an AC generator is parallel to the field, in which is it rotating, the flux linked with it is zero, while induced emf is maximum.
- The angle between the axis of the coil and the magnet will be 180 degrees when it is parallel.
- The flux linkage will be zero in this case.
- The emf in the magnet and the coil is maximum.
