In induction motor, percentage slip depends on__________?
Correct answer: C. copper losses in motor
- A. supply frequency
- B. supply voltage
- C. copper losses in motor
- D. none of the above
Explanation
Slip equals rotor copper loss divided by rotor input power, so it changes with the rotor copper loss as the load changes. Supply voltage and frequency affect operation too, but copper loss is the direct relation tested here.
