Capacitor helps a motor generate a starting torque. once the torque is produced and motor rotates capacitor acts as a current path. technically capacitor creates a phase difference.
It is most likely used in conjunction with a starting winding in a single-phase motor to make it start the correct way.
Be certain to observe the exact same polarity as the old one. A capacitor does have plus and minus leads. Should an old defective ceiling fan transformer be replaced by a capacitor?
No, it is the capacitors effect upon the motor's winding that starts the fan to turn.

Ceiling fans use less electricity on low speed than they do on medium and high speed. Capacitors are used to control the various fan speeds. The capacitor limits the amount of electricity supplied to the fan motor. When less electricity is sent to the windings in the motor, the fan spins at a lower RPM. The result is a slower speed and less airflow. However, some fans move almost no air at low speeds, so it is important to know what the CFM/watts is for the ceiling fan in question so you can compare the performance at any given speed relative to the amount of electricity used
A capacitor start motor is used in a ceiling fan.
capacitor is a power cell used to generate electricity in the motor of ceiling fan
If you are referring to a ceiling fan it is in the bell housing where the fan connects to the electrical box at ceiling level.

by changing the polarity of capacitor of single phase ceiling fan can we change the direction of rotation from anticlockwise to clockwise

typically, you don't attach capacitors to ceiling fans ( 120V or 240V ). A capacitor would only be used for one of two reasons. 1. to reduce the noise on the AC in your home or 2. to reduce the spikes to your fan... neither of these make any sense.
A capacitor always stores charges unless its damaged
There are a variety of capacitor sizes in ceiling fans. The capacitor is dependant upon the characteristics of the fans motor. Whether it is a single speed, two speed or three speed. If you think it is the capacitor at fault for the fan not operating, take the fan down and open it up. This will give you the exact sizing for your fan.See sources and related links below.

The capacitor in a ceiling fan is a small fuse like device which helps the fan to slow down or rotate faster. It is normally inserted into the ceiling unit of fan just about the fins.
Probably not. A ceiling fan's motor converts electricity into mechanical motion. While many electrical motors can also be run as generators ceiling fan designers most likely wouldn't include that feature in designs. Ceiling fans also have a capacitor to help generate enough torque to start a fan. Sending electricity back through a capacitor in the opposite direction is not recommended.
