find Ztot in rectangular form B) find Ztot in polar form C) find V1 or VL in polar for. ( use voltage divider rule or ohm law).

6 The circuit in Figure P7.56 shows the use of ideal transformers for impedance matching. You have a limited choice of turns ratios among available transformers. Suppose you can find transformers with turns ratios of 2:1, 7:2, 120:1, 3:2, and 6:1. If Z, is 475Z – 25°2 and Z, must be 2672 – 25°, find the combination of transformers that will provide this impedance. (You may assume that polarities are easily reversed on these transformers.)
