This calculator can be used for making LC oscillator, tuners, bandpass filter or frequency mixers. Oscillator and bandpass filter can be used in RF and others. LC parallel resonant circuit are also used as current amplification circuits. Series resonant circuit provides voltage amplification. The resonant frequency of parallel LC resonant circuit is given by,\( f_r = \frac{1}{2 \pi \sqrt{LC}} \)This equation is derived with the fact that at the resonant frequency the inductive reactance(\(X_L\)) is equal to the capacitor reactance(\(X_C\)). That is we have,\(X_L = X_C\)or, \(2 \pi f_r L = \frac{1}{2 \pi f_r C}\)rearranging we get, \( f_r = \frac{1}{2 \pi \sqrt{LC}} \) Below are some tutorials where the LC parallel resonant circuit calculator can be used. - How does Single Diode Modulator Circuit work?- Simple Amplitude Modulation (AM) circuit using Single Diode Modulator Tags: Calculator 4.94 / 169 rates Facebook Tweet CopyLink Copied Share
