The induced e.m.f. in a synchronous motor working on leading power factor will be_____________?

Correct answer: A. more than the supply voltage

  • A. more than the supply voltage
  • B. less than the supply voltage
  • C. equal to the supply voltage
  • D. None of these

Explanation

For a synchronous motor at leading power factor, the reactance-drop phasor causes the internal induced emf to exceed the terminal supply voltage in magnitude. This is the usual overexcited operating condition.
