Answer to Question #159178 in Electric Circuits for Yolande

Question

Give one practical example of the use of a capacitor, explaining how the properties of the capacitors are utilized in the example you choose.

Answer 1

Answer

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.
