An RLC series circuit is connected to a 120-Vrms, 60Hz line. The inductance is 0.05 H, the average current is 11A and the current leads the voltage by 45 degrees.What is the resistance?What is the capacitance?Find the average voltage of each element. Show all the voltages (for R, L, C, and total) and also the current on a phasor diagram.If we want to make the power factor 1, should we add capacitance or inductance to the circuit? Find the magnitude of this extra capacitance or inductanceWhen the power factor is 1(L and C from previous part), what is the average current?
