INTRODUCTION 
Q is the quality factor, or a figure of merit, for a resonant circuit. Q for unloaded resonant circuits:
X = reactance in ohms (inductive or capacitive) In unloaded resonant circuits, the greatest power loss occurs in the resistance of the resonant circuit.
R = parallel load resistance To calculate reactance:
2pi = 6.28
Q= 75.1 In loaded resonant circuits, the circuit delivers power to a load. The power dissipated by the resistance of the resonant circuit is negligible in comparison.
