"Because the 'XL' is really sq.rt (XL^2 + RL^2) and the 'XC' is really
sq..rt (XC^2+ RC^2) where RL and RC are the series resistances of the inductor
and capacitor respectively. If you take the case where Q=5, then the 'XL'
becomes an impedance of 1.1XL with a phase angle of 78.7degrees, rather than 90"
Whoa Nellie! The way reactances are taught here are: XL) XL=2*p*f*L where
as p= 3.14 (for all practical purposes), f= frequency, and L= inductance in
henries. Then XL is the reactive component in ohms. XC= 1/2*p*f*C, where C=
capacitance in farads. Like wise, XC is the reactive component.
Never in the course of any electronics training and basic AC theory (at
least here anyway) has the circuit resistive component been used in computing
capacitive or inductive reactance. It IS used in determining the overall
"circuit Q", but it is done completely and independently of the reactance
computations.
