Consider an rlc series circuit with an l = 1.80 h inductor , a c = 0.900 f capacitor , and a r = 300  resistor. the source has terminal rms voltage δvrms = 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 (i) r = 300 , (ii) 30.0 , and (iii) 3.00 . what happens to the resonance width as the resistance is decreased?
