In a D.C. generator, the iron losses mainly take place in___________/
Correct answer: D. armature rotor
- A. yoke
- B. commutator
- C. armature conductors
- D. armature rotor
Explanation
Iron losses consist of hysteresis and eddy-current losses, and they occur mainly in the laminated armature core as it rotates through the magnetic field. The commutator and armature conductors mainly contribute to other losses.
