Q. Which of the following is dynamic braking?

  • (A) reversal of field connections
  • (B) reversal of armature connections
  • (C) addition of equal and opposite field
  • (D) removal of armature circuit from current machine circuit
💬 Discuss
✅ Correct Answer: (D) removal of armature circuit from current machine circuit
Explanation: reversal of the connections of armature is the method called plugging. in dynamic braking we remove the armature circuit and connect it to different resistor, with field circuit still connected to the external supply.
