Consider a simple, transformer with two windings. Find the current provided by the voltage source.

  • Winding 1 has a sinusoidal voltage of ° applied to it at a frequency of 60Hz.
  • The combined load on winding 2 is

Solution

, so

Therefore,

Now the Thevenin equivalent impedance, , is found through the following steps:

Now, substituting:

Since ,

Since this is an ideal transformer, it can be modeled by this simple circuit: Ideal Circuit.jpg

Andrew Sell - Chris, everything looks fine, though I would do some extra formatting if possible to help make the problem flow a little smoother as you read it.
