I hope so!I understand this very well.
Apply it to the solution of the exercise in post #113I am asking what to do with it now?
Again, impedance may be regarded as the EMF to current ratio --- Further to that, the 'clues' offered by @Aleph(0) and myself regarding the relationship of the transformation ratio to system 'Q' in this type of network should render the solution obvious!!!
System Quality Factor (Q) = √(transformation_ratio-1)
--Emphasis added---Q is proportion of reactance to resistance so like Qp=R/X and Qs=X/R
