Calculate the transformer ratio of the transformer in Problem 18.23 when it is used as a step-up transformer.
Problem 18.23 The high-voltage side of a step-down transformer has 800 turns, and the low-voltage side has 100 turns. A voltage of 240 VAC is applied to the high side, and the load impedance is 3 ? (low side). Find: a. The secondary voltage and current. b. The primary current. c. The primary input impedance from the ratio of primary voltage to current. d. The primary input impedance.
