Hi all,
This is probably not an incredibly smart question but I have to ask regardless!
If you consider a transformer to be two coupled inductors, and if you consider the secondary to be loaded with a resistor then you have the situation where The resistor and secondary winding share the same current AND the same voltage across their terminals. So while the load resistor insists on voltage and current being in phase (being a non reactive component), if the secondary is truly an inductor, it should force voltage and current to be in quadrature. Since both situations cannot be satisfied, and a simulation shows - somehow - that the resistor "wins", it means we have an inductor with voltage and current 180 degrees out of phase rather than the 90 degrees that physics tells us should exist.
What am I not getting here?
Thanks!
