    Im having trouble getting to grips with calculating the value of z for calculating the new impedance in a balanced star load to ascertian the pf. the trouble im having is calculating the correct polar to rectangular form. i have a capacitor in parallel with a resistor which is in series with an inductor.

    Find the imopedance of the capacitor, put it in parallel with the imopedance of the resistor and then add their result to the impedance of the inductor.
