The power factor of a synchronous motor __________

The power factor of a synchronous motor __________ Correct Answer Improves with an increase in excitation and may even become leading at high excitations

From inverted V-curve we can see when the power factor is leading power factor decreases when the excitation increases and it is over-excited conditions and when power factor is lagging if the motor power factor is increasing if excitation increases.
