If 0.3 A flows in the secondary and 30 A flow in the primary of a perfectly matched, ideal transformer, what i

Answer 1

Your question is missing. However, I can say that there are no power losses in an ideal transformer. Therefore, if the ratio of the currents between primary and secondary windings is 100:1, then the ratio of the voltages must be 1:100. That is to say that the voltage across the secondary is 100 times greater than the voltage across the primary.

Answer 2

You would have a very high secondary voltage.
