In a D.C. shunt motor, speed is______________?
Correct answer: A. independent of armature current
- A. independent of armature current
- B. directly proportional to the armature current
- C. proportional to the square of the current
- D. inversely proportional to the armature current
Explanation
In a shunt motor, the field winding is connected across the supply, so its flux remains nearly constant. Consequently, speed changes very little with armature current and is treated as approximately independent of it.
