Why we use a capacitor in an electric fan?
Answer:
1. Capacitor is used for both starting the electric fan and improving power factor.
2. The voltage taken by the fan during running has lagging power factor and in order to run the fan we need leading power factor. The capacitor increases the power factor. So we use capacitor in fan to increase its power factor.
3. To give a quick start-up for any instrument, capacitor is used in electronics, by using capacitor in the start-up there is a charge accumulation in between the plates of capacitor,whichis discharged again and gives a quick start to the instrument otherwise we have to use a very high voltage to the instrument
