Problem
A coil of resistance 20 Ω and inductance 2.0 H is connected in series with a capacitor of 5.0 μF to a 200 V (rms) ac source.
(i) Calculate the natural (resonant) angular frequency of the circuit.
(ii) Determine the rms current in the circuit at resonance.
(iii) Evaluate the quality factor of the circuit.
(iv) Find the upper and lower half-power angular frequencies and hence the bandwidth.
