15.4 Exercise 13

Avg difficulty 2.5

An RLC series circuit has an impedance of 60Ω60 \Omega 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?
