Q. phase with the main voltage then speed will

  • (A) increase
  • (B) decrease
  • (C) remain unchanged
  • (D) first increases then decrease

✅ Correct Answer: (B) decrease
Explanation: in the rotor injection method, when an external voltage is in opposite phase with the main voltage net voltage decreases and the value of slip increases and the value of rotor speed decreases.
