LC Resonant Circuit Calculator

This calculator determines the values of inductance (LL) and capacitance (CC) for an LC resonant circuit with specified source and load resistances. Given inputs such as the resonant frequency (frf_r), quality factor (QQ), source impedance (RsR_s), and load impedance (RlR_l), the calculator first computes the parallel resistance (RpR_p) using Rp=Rs×RlRs+RlR_p = \frac{R_s \times R_l}{R_s + R_l}. The parallel reactance (XpX_p) is then calculated as Xp=RpQX_p = \frac{R_p}{Q}. Finally, the inductance and capacitance are found using L=Xp2πfrL = \frac{X_p}{2 \pi f_r} and C=2πfrXpC = \frac{1}{2 \pi f_r X

Some example usage of this online LC parallel resonant circuit calculator are as follows.
