decrease both armature current and power factor
decrease armature current but increase power factor
increase armature current but decrease power factor
increase both its armature current and power factor
Answer is Wrong!
Answer is Right!
The correct answer is: C. increase armature current but decrease power factor.
When a load is applied to a synchronous motor, the motor draws more current from the power supply. This increased current causes the motor’s magnetic field to become stronger, which in turn causes the motor to turn faster. The faster the motor turns, the greater the load it can carry.
However, the increased current also causes the motor’s power factor to decrease. This is because the motor’s inductive reactance causes it to draw a current that is out of phase with the voltage. This out-of-phase current causes the motor to waste power,
