In case of the induction motors the torque is___________?
Correct answer: D. directly proportional to slip
- A. inversely proportional to (Vslip)
- B. directly proportional to (slip)2
- C. inversely proportional to slip
- D. directly proportional to slip
Explanation
In the normal low-slip operating region, rotor reactance is small compared with rotor resistance, making torque approximately directly proportional to slip. The exact torque-slip curve is not linear at high slip, but option d is the standard operating-region relation.
