Explanation:
Capacitor start single-phase motors are used in applications where high starting torque is required. They are commonly used in air compressors, pumps, and other heavy-duty machinery.
The capacitor start single-phase motor has two windings: the main winding and the starting winding. The main winding is designed to handle the normal running load, while the starting winding is designed to provide the high starting torque required for the motor to start.
The starting winding is connected in series with a capacitor to create a phase shift between the current and voltage in the winding. This phase shift creates a rotating magnetic field that produces the high starting torque.
In capacitor start single-phase motors, the current in the starting winding leads the voltage. This means that the current reaches its peak value before the voltage reaches its peak value.
This phase difference is necessary to create the rotating magnetic field required for the motor to start. Without the phase difference, the motor would not be able to produce the high starting torque required to overcome the inertia of the load.
Conclusion:
In conclusion, the correct answer to the question is that in capacitor start single-phase motors, the current in the starting winding leads the voltage. This phase difference is necessary to create the rotating magnetic field required for the motor to start and produce the high starting torque required to overcome the inertia of the load.
