When load on a synchronous motor running with normal excitation is increased, armature current drawn by it increases because
Back e.m.f. Eb becomes less than applied voltage V
Power factor is decreased
Net resultant voltage ER in the armature is increased
Motor speed is reduced
Net resultant voltage ER in the armature is increased
Quick Summary: Practice and solve "When load on a synchronous motor running with normal excitation is increased, armature current drawn..." for Electrical - Machine. The correct answer is Option C: Net resultant voltage ER in the armature is increased. Detailed step-by-step solution, conceptual clarity, and formulas on Examoogle.
