Regenerative method of braking is based on that___________?
Correct answer: C. back e.m.f. of rotor is more than the applied voltage
- A. back e.m.f. is less than the applied voltage
- B. back e.m.f. is equal to the applied voltage
- C. back e.m.f. of rotor is more than the applied voltage
- D. none of the above
Explanation
Regenerative braking occurs when the motor operates as a generator and returns power to the supply, requiring its generated back EMF to exceed the applied voltage. Thus, the rotor back EMF is greater than the applied voltage.
