In a series-connected R-L-C circuit, the frequency is 50 Hz, while the impedance of the circuit is 60 Ω and the power factor is 0.72. The source voltage is behind the current. An actuator (coil) or a capacitor must be connected to the circuit to increase the power factor. Find the value of the element that needs to be connected in order for the power factor to be 1.
