← ScienceWhich phenomenon reduces generator output when inductive load increases?
A)Armature reaction reduces air gap✓
B)Stator slots generate cogging torque
C)Eddy currents heat rotor laminations
D)Magnetic hysteresis increases core saturation
💡 Explanation
Armature reaction weakens the main magnetic field, because the armature current generates its own magnetic field opposing the main field; therefore, output voltage drops, rather than other inefficiencies or effects affecting torque.
