An inductor and a capacitance LC resonant circuit composed of a LC series circuit and the LC parallel circuit of two. Ideal LC series resonant circuit was 0 when the external resistance, the ideal parallel LC resonant circuit when the external impedance of infinity. Using this feature can be made of all kinds of LC circuit oscillator circuit, selective frequency network, filtering networks. Resonant frequency f0 has the following formula:
Enter L, C, calculate F:
