This is due to the inductive nature of the rotor windings.<\/p>\n<p>The lagging power factor of a single-phase induction motor can be improved by using a power factor correction capacitor. A power factor correction capacitor is a capacitor that is connected to the motor in parallel. The capacitor provides a leading current that helps to offset the lagging current of the motor. This improves the power factor of the motor and reduces the amount of reactive power that is drawn from the power grid.<\/p>\n<p>Option B is incorrect because a single-phase induction motor is not always leading.
