Problem
In an experiment on a series LCR circuit the inductance and capacitance are fixed at L=0.10H and C=25μF respectively. The applied sinusoidal voltage has a peak value of 200V. When the supply frequency is varied, the maximum rms current observed in the circuit is 2.0A.
(i) Calculate the resistance present in the circuit.
(ii) Determine the quality factor of the circuit at the frequency that produces the maximum current.
(iii) Compute the bandwidth (in Hz) corresponding to this resonance peak.
