Parameter Series Circuit Parallel Circuit
Impedance Minimum Z=R Maximum ZO  =L/CR
Nature of Circuit Resistive Resistive
Power Factor Unity (1) Unity (1)
Current that’s drawn from the source $Maximum:\ I=\frac{V}{R}$ $Maximum:\ I=\frac{V}{L/CR}$
Resonant Frequency $f_r=\dfrac{1}{2\pi{}\sqrt{LC}}$ $f_r=\dfrac{1}{2\pi{}\sqrt{LC}}$
Magnification Voltage magnification Current magnification
Q-factor $Q=\frac{1}{R}\sqrt{\frac{L}{C}}$ $Q=\frac{1}{R}\sqrt{\frac{L}{C}}$
Type of circuit Acceptor Rejector
