Consider an L-R-C series circuit with a 1.80 H inductor, a 0.900 x 10^-6 capacitor, and a 300 ohm resistor. The source has terminal rms voltage 60.0 and variable angular frequency w.
a) What is the initial resonance angular frequency W of the cicuit?
b) What is the rms current through the circuit at resonance, rms I?
c) For what two values of the angular frequency, W1, and W2, is the rms current half the resonance value?
d) The quantity W1-W2 defines the resonance width (absolute value). Calculate rms I and the resonance width for R = 300 ohm, 30.0 ohm, and 3.00 ohm.
