I have been given a resonant frequency of 95KHz, a bandwidth of 1150Hz, a resistance of 3Ω and a voltage of 5V, I've calculated the series capacitance and inductance, by the use of the formulas stated below, however not sure if it's right. Can you give me the formulas for the parallel resonance? I'm not sure how to work that out. Series Resonance Circuit Qr = fr/f2-f1 = 95KHz/1150Hz = 82.609 Qr = Xl/R ∴ Xc = Qr*R = 82.609*3Ω = 247.826Ω Xc = 247.286Ω Xc = 1/(2πfC) ∴C = 1/(2πfXc) = 1/(2*π*95KHz*247.82) = 6.76nF Xl = 2πfL ∴ l = Xl/(2πf) = 247.826/(2*π*95KHz) =415μH ^ Is this right? ^ Parallel Resonance Circuit Not sure what to do here.
