The Resonance Width. Consider an L-R-C series circuit with a 1.80-H inductor, a 0.900-μF capacitor, and a 300-Ω resistor. The source has terminal rms voltage Vrms = 60.0 V and variable angular frequency ω. (a) What is the resonance angular frequency ω0 of the circuit? (b) What is the rms current through the circuit at resonance, Irms-0? (c) For what two values of the angular frequency, ω1 and ω2, is the rms current half the resonance value? (d) The quantity |ω1 - ω2| defines the resonance width. Calculate Irms-0 and the resonance width for R = 300 Ω, 30.0 Ω, and 3.00 Ω. Describe how your results compare to the discussion in Section 31.5.
