An L-R-C series circuit, R= 160 Ω, L= 0.700 H, and C= 1.90×10-2 μF. The source has a voltage amplitude of 160 V and a frequency equal to the resonance frequency of the circuit. What is the average power delivered by the source? The capacitor is replaced by one with a capacitance of C=4.00×10-2 μF and the source frequency is adjusted to the new resonance value. Then what is the average power delivered by the source?
