Answer in Electric Circuits
In ceiling fan capacitor is used.
ceiling fan have a single phase induction motor .but this motor does not start by itself. It requires external force to run it initially.
So to overcome this problem capacitor is used. It is connected across a part of the winding in the fan motor. The capacitor splits the current in different phases or it creates a phase difference between the windings. A magnetic field is produced which makes the rotor rotate in the direction of the generated magnetic field.
