3) The quality factor Q is a dimensionless paramater involving the relative values of the magnitudes of the at three impedances (R, X_{L}, X_{C}). Since Q is calculatedat resonance, X_{L}, X_{C} and only twoimpedances are involved, Q=≡ω_{0}L/R is definedso that Q is large if the resistance is low. Calculate the Q of an LRC series driven at resonance by an applied voltage of of V=V_{0}sin(ωt), where V_{0}=5 V. The resistance, inductance, and capacitance are R =0.27 Ω, L= 4.30E-03H , and C=2.20E-06 F, respectively.
