RC Series to Parallel Impedance Transform Calculator

Convert a series RC (or RL) network to its equivalent parallel representation.
The conversion formulas are:
$R_{p a r a l l e l} = \frac{R^{2} + X^{2}}{R}$ and $X_{p a r a l l e l} = \frac{R^{2} + X^{2}}{X}$

* Enter the series resistor (Ω) and series reactance (Ω). (For capacitive reactance, enter a negative value.)
