A 3-phase synchronous motor with constant excitation drives a certain load drawing electrical power from an infinite bus at leading power factor. If the shaft load decrease

The power angle increases while power factor decreases

The power angle decreases while power factor increases

Both power angle and power factor increase

Both power angle and power factor decrease
