Therefore, we minimise the effect of that inductance by making L

(and consequently L

and

M too)

very large compared to the maximum value of Z

L

that we may use. This is done by using a large cross-

section iron core and a large number of turns in both windings keeping the turns ratio at the desired

value. An ideal transformer is an idealised model for such a transformer.

An  ideal  transformer  is  a  two-winding  transformer  with  perfect  coupling  (k  = 1)  and 

infinite self and mutual inductance values (L

Thus, the equations ...
