A synchronous motor is running on a load with normal excitation. Now if the load on the motor is increased
A)power factor as well as armature current will decrease
B)power factor as well as armature current will increase
C)power factor will increase but armature current will decrease
D)power factor will decrease and armature current will increase

When the load on a synchronous motor is increased, the motor requires more torque to maintain its synchronous speed. To produce more torque, the armature current increases. However, as the load increases, the angle between the rotor and the stator magnetic field (power angle) also increases, leading to a decrease in the power factor.
