An L-R-C series circuit has a resistance of 147 Ω, an inductance of 0.780 H and a capacitance of 1.40×10-2 µF. The source has voltage amplitude of 151V and a frequency equal to the resonance frequency of the circuit.
Part A Calculate what is the power factor?
Part B Calculate the average power delivered by the source?
Part C The capacitor is replaced by one with a capacitance of 3.40×10-2µF and the source frequency is adjusted to the new resonance value. Then find the average power delivered by the source?
