dear ac contains +ve and -ve cycles now in wat direction
fan will move.
the capacitor increases the amplitude of +ve cycle by
giving it the stored magnetic energy and fan starts
rotating in +ve directioni.e anticlockwise


do one thing change the connections of capacitor and wat
will u see is tha t the fan starts rotating in opposite
direction


do one more thing remove the capacitor and make the
connections complete without capacitor u see the fan will
