LC Resonant Frequency Calculator

LC Resonant Frequency Calculator

A circuit with an inductor (L) and capacitor (C) connected in parallel or series will have a resonant frequency at which their impedances are equal. Given two of the three values—inductance, capacitance, or resonant frequency—this tool will calculate the missing third variable.
