Q. b) DC generator

  • (A) reduce armature voltage
  • (B) increase armature voltage
  • (C) increase field current
  • (D) decrease field current

✅ Correct Answer: (D) decrease field current
Explanation: in ward leonard speed control method, speed can be increased above base value by weakening of the field, which can be done by lowering field current value. by increasing armature voltage speed can be increased but this is not employed in ward leonard method.
