Answer / saravanan.p

Due to single phase, the fan will not rotate. The capacitor
is having leading power factor.That is +90 degree leading
from phase voltage.

Due to capacitor, The single phase splits into two phases.
This phase difference use to stimulate the fan to rotate.

Answer / mahesh goud

slipt the phese
due to single phase motor not self start

Answer / arunava

It simply splits the phase angle like a two phase system,
during startup.

Answer / shailesh singh

Single phase motor are not self starting for this we
produce phase split between voltage and current by using
capacitor

Answer / ghaniullah khan

Ac supply given to a equipment having winding then there is a lagging power factor then we use a capacitor which has leading power factor then voltage and current are in phase into some extent which increase power factor.

Answer / mallikarjuna reddy

usually fan having two types of windings,i.e starting wdg &
Running wdg.
whenever we switch on the supply the fan may take the
moment slowly due to starting wdg,at this time fan requires
some reactive power(because fan wdg acts as inductive
load),at this time capacitor supplies this reactive
power.then only the fan will rotates with its own RPM.

Answer / prathamesh

For increasing power factor.

Answer / mousumi

AT STARTING CONDITION CAPACITOR PRODUCE TORK. IN RUNNING
CONDITION CAPACITOR IS ALSO WORK FOR RUNNING PURPOSE.
