capacitor is for startin purpose

Answer / dipen dalsaniya

Domestic fan has to winding one starting and other one
running wdg.so capacitor used to for the purpose of
starting.

Answer / sanjay dalvi

to genrate rotating field in single phase motor Capacitor
is used as a starting winding;when motor rotates at 80 % of
full speed ;Starting winding cut off from circuit & fan
motor runs at rated speed.

Answer / dilli babu

fan is a capacitor start and capacitor run motor.
Basically single phase induction motor is not a self start motor. Fan having starting coil and running coil. The capacitor is connected to starting coil. when we are giving supply to the fan, because of the capacitor charging and discharging charector the current flows through the starting coil and capacitor and it starts rotation.

Answer / smita

In Domestic Fan working, it consistes of an induction motor
for fan rotation, and capacitor is used for power factor
control.

In an electrical conductor, if current flows because of flow of electrons, then why not the conductor gets thinner day by day???
