Dear fellows,
 

                   as all ovr the world three phase power

distribution is used , then why a capicitor is used in electric fans to

produce

                    a phase sequence to meet the requirement.

ha ha ha ha khushal , well said , anyway sorry to laugh ! it is a very basic question a first yr student ask. The answer is , in single phase fan the capacity does not act as a power factor, Basically it splits the phase , so that it can rotate. if you take out the capacitor from the fand and start it , it will pulsate and will not rotate but once u provide the rotation by a hand and it will start rotating.

ha ha ha , see the quadrature theory in the basic electrical engineering.
