In a D.C. shunt motor, under the conditions of maximum power, the current in the armature will be_____________?
Correct answer: D. more than full-load current
- A. almost negligible
- B. rated full-load current
- C. less than full-load current
- D. more than full-load current
Explanation
For maximum mechanical power in a shunt motor, the armature current is approximately half the short-circuit current, which is normally far above the rated full-load current. Thus the motor would operate with an armature current greater than full-load current.
