![[Resistor in parallel with Inductor]](../../images/inductor-resistor-series1.gif){kind=small}
This calculator finds the complex impedance (real and imaginary imaginary values) of a capacitor and an inductor in parallel.
The complex impedance (Z) (real and imaginary, or resistance and reactance) of an inductor and a resistor in series at a particular frequency can be calculated using the following equation.
![[Equations for Xl and Z]](../../images/inductor-resistor-series2.svg "Inductor and Resistor in Series Equation")
Where:
f is the Frequency in Hz
L is the Inductance in Henries
R is the Resistance in Ohms
