self starting problem of single phase AC motors. Single
phase isn't able to create torque by different magnetic fields.
So capacitors etc. are used to overcome this problem.

Answer / shahidniazi

when we use only single winding then no rotating flux so in
single phase motor is not actually single phase but split
phase mean 2 windings so that will produce rotating field
and rotor will move.

what is leading power?
