a single phase motor takes 50 A at a power factor of 0.6 lagging from a 240V, 50 Hz supply. Determin a.) the current taken by the capacitor in parrallel with the motor to correct the power factor to unity, and b.) the value of the supply current after power factor correction.

i worked out the Ic by

pf=cosO

0=cos -1 (0.6)

0=53.13

true power=Vcoc0

=240 cos 53.13

144W

Q=true power * tan 0

Q=144 * tan 53.13

Q=191.99 VA

Ic=Q/V

Ic=191.99/240

Ic=0.799A

but am struggling with the value of the supply current question b

i have calculated Xc as 300.38 ohms and C as 0.106uF but dont know where to go from here

can anyone help

cheers
