Answer: A capacitor in a fan is used to create a phase difference between the current flowing to the motor’s start and run windings, facilitating the motor’s rotation and providing the necessary torque. Reasoning: The capacitor in a fan serves to create a phase shift in the current supplied to …

Answer: When an induction motor operates at synchronous speed, it ceases to induce rotor currents, leading to loss of torque and failure to start. Reasoning: Induction motors rely on the relative motion between the rotating magnetic field and the rotor to induce currents and generate torque. At synchronous speed, this …
