A parallel RLC circuit is shown in Fig. 10.23. At parallel resonance condition determine the resonant frequency, quality factor and resonant impedance.
Step-by-Step
The resonant frequency is calculated as,
f_{0}={\frac{1}{2\pi}}{\sqrt{{\frac{1}{0.8\times0.9\times10^{-6}}}-{\frac{5^{2}}{0.8^{2}}}}}=187.56\,\mathrm{Hz} (10.172)
The quality factor is determined as,
Q_{p}={\frac{2\pi\times187.56\times0.8}{5}}=188.56 (10.173)
Resonance impedance is calculated as,
Z_{r}={\frac{0.8}{5\times0.9\times10^{-6}}}=177.78\,{\mathrm{k}}\,{ \mathrm {Ω}} (10.174)
