Answer : Ans: D To give starting torque and to maintain speed.

Answer : In a ceiling fan employing capacitor run motor secondary winding surrounds the primary winding.

Answer : The wattage rating for a ceiling fan motor will be in the range 50 to 150 W .

Description : Why is a capacitor used in a ceiling fan ?

Answer : For splitting phase so that a rotating magnetic field will be produced & as per Lenz's law a torque will be created & rotor starts rotating. In single phase if capacitor is not used for split phase then a pulsating mag. field is produced which is unable to produce torque on rotor
