How is the Q of an RLC parallel resonant circuit calculated?
Reactance of either the inductance or capacitance divided by the resistance
Reactance of either the inductance or capacitance multiplied by the resistance
Resistance divided by the reactance of either the inductance or capacitance✓الإجابة الصحيحة
Reactance of the inductance multiplied by the reactance of the capacitance
الشرح
In the parallel case the resistance appears across the tank rather than in series with it, so the roles of R and X are inverted relative to the series formula. Q is therefore the resistance divided by the reactance of either reactive element, which are equal at resonance.
