Transformer Impedance Reflection Demonstration
Layton, William
Physics Teacher, v52 n7 p426-427 Oct 2014
Questions often arise as to how a device attached to a transformer can draw power from the electrical power grid since it seems that the primary and secondary are not connected to one another. However, a closer look at how the primary and secondary are linked together magnetically and a consideration of the role of Lenz's law in this linkage may help to clear up this confusion.
