Single Phase Transformer Tutorial: Get Help & Answers!

[ns01]

I have a single phase transformer tutorial that I am struggling with, I was wondering if anyone could help.
Attached is the equivalent circuit diagram
I have values for all varables, and have a few questions,

When the circuit is reduced to its approximate form (ie, secondary side referred to the primary side), do rm , Xm and N1/N2 remain the same.

And given the transformer is operating at a constant primary voltage of V1, how do I calculate the primary current, the primary real power, the primary power factor and the secondary voltage.

You need to reflect the secondary quantities to the primary side. Then you can solve the primary circuit, neglecting the transformer.

Have you learned about reflection operations using ideal transformers?
