So I've been confused about transformers lately. In searching for some information regarding the basic transformer, I came across this: http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/transf.html#c1. While this page was informative, I am still left confused in regards to one point in particular.(adsbygoogle = window.adsbygoogle || []).push({});

Assuming the two windings are not touching and are simply magnetically coupled, shouldn't the current in the secondary loop be given by the induced voltage divided by the resistance in the loop? Thus, an increase in voltage, such as in a step-up transformer, should generate a larger current in the secondary loop. This line of reasoning, however, comes into conflict with the link's energy conservation logic, which claims that an increase in voltage should result in a lower current in the secondary loop. I see the validity in their reasoning, but I fail to see the flaw in mine.

I would greatly appreciate any and all help. Thanks in advance.
