An L-R-C series circuit, R=150 ohms, L= 0.750H, and C= 1.70x10^-2uF. The source has a voltage amplitude of 140V and a frequency equal to the resonance frequency of the circuit.
A) What is the power factor?
B) What is the average power delivered by the source? (answer in W).
C) The capcitor is replaced by one with a capcitance of C= 3.80x10^-2uF and the source frequency is adjusted to the new resonance value. Then what is the averge power delivered by the source? please show work.
