The complex impedance (Z) (real and imaginary) of an inductor and a resistor in series with a parallel capacitor at a particular frequency can be calculated using the following formulas.

Where f is the Frequency in Hz

C is the Capacitance in Farads

L is the Inductance in Henries

R is the Resistance in Ohms
