RC Parallel to Series Impedance Transform Calculator

Convert a parallel RC network to its series equivalent at a given frequency using:
$R_{s} = \frac{R}{1 + (ω R C)^{2}} and C_{s} = \frac{1 + (ω R C)^{2}}{ω^{2} R^{2} C}$ where $ω = 2 π f$ .

* Enter resistor value (Ω), capacitor value (F), and frequency (Hz).
