to make the fan motor self stating and to inprove the power
factor capacitor used in fan not resitor.

Answer / qurrat ul ain

Capacitor is used in series with the auxiliary winding of the fan motor to make the phase difference between main winding current and auxiliary winding current equal to 90 degrees. This makes the fan motor self-starting. The auxiliary winding along with the capacitor may be disconnected after starting. However, generally the capacitor and auxiliary windings are allowed to remain connected in order to improve the motor performance, the power factor, in particular.
