6.27. A series circuit consists of a resistance R = 1 ohm, an inductive reactance jX=j4 ohms and a third impedance Z. If the applied voltage and resulting current are V = 5045° V and I = 11-2/ 108-4° A, what is the impedance Z? Ans. Z=1-j8Q www 90 v = 120 120 V Fig. 6-43 00 63-5° 45° 25° 39-05 I 41-2 A Z 7-91 A 85 V 250 V Fig. 6-44 Fig. 6-45
