From Examples 19-4 and 19-7 respectively, V_{th}= 11.2\angle 63.4°VandZ_{th}= 44.6\angle 63.4°\Omega . In rectangular form, the impedance is
Z_{th}= 20 \ \Omega + j40 \ \OmegaThis form indicates that the impedance is a 20 Ω resistor in series with a 40 Ω inductive reactance. The Thevenin equivalent circuit is shown in Figure 19-25.
