Question

Consider the power dissipated in a series R-L-C circuit with R=3600, L = 120mH, C=0.800μF, V = 50V, and w=11300rad/s. The current and the voltages in this circuit are not in phase with each other. Using the values given, the phase angle was found to be 74°, and the current amplitude I was found to be 3.9x10-2 A. Calculate the power factor and the average power to the entire circuit and to each circuit element. If the inductance L in this circuit could be changed, what value of L would give a power factor of unity?
