The manufacturer calculates that the transformer of Problem 2.7 has a secondary leakage inductance of 0.225 mH.

Question:

a. Calculate the magnetizing inductance as referred to the secondary side.

b. A voltage of 266 V, 60 Hz is applied to the secondary. Calculate (i) the resultant open-circuit primary voltage and (ii) the secondary current which would result if the primary were short-circuited.
