In an L-C-R ereis circuit R=150Omega, L=0.0750 H and C=0.0180muF . The source has voltage amplitude V=150V and a frequencey equal to the resonacne frequency of the circuit. (a) What is the power factor ? (b) What is the average power delivered by the source? (c) The capacitor is replaced by one with C=0.0360muF and the source frequency is adjusted to the new resonance value. Then, what is the average power delivered by the source?
