Unformatted text preview: rrent and voltage for 3 different operating conditions: (i) load impedance of 40 ohms at 0.8 power factor lag, (ii) load impedance of 40 ohms at unity power factor, (iii) load impedance of 40 ohms at 0.8 power factor lead. Answers should be given as complex number (magnitude and angle in degrees); assume the primary voltage at an angle of 00, i.e., as the reference. 2. For this same transformer, but with the following operating condition, what is the efficiency of the transformer? Is = 6.23 @ ‐300 amps V...
