For what value of the phase angle ϕ between the voltage output of an ac source and the current is the average power output of the source a maximum? An RLC series circuit has an impedance of 60Ω and a ...For what value of the phase angle ϕ between the voltage output of an ac source and the current is the average power output of the source a maximum? An RLC series circuit has an impedance of 60Ω and a power factor of 0.50, with the voltage lagging the current. (a) Should a capacitor or an inductor be placed in series with the elements to raise the power factor of the circuit? (b) What is the value of the reactance across the inductor that will raise the power factor to unity?
