Q. Efficiency of Ward Leonard method is

  • (A) higher than rheostatic control method but lower than shunted field control method
  • (B) lower than rheostatic control method
  • (C) higher than rheostatic control method and shunted field control method
  • (D) depends on load
💬 Discuss
✅ Correct Answer: (C) higher than rheostatic control method and shunted field control method
Explanation: unlike all other methods, external resistance is not added in the circuit of control system. thus, efficiency of ward leonard control method is always highest at various different speeds.
