I need this

and this is my code so far:

I have played a bit with the american / european current and voltage arrow, but can't make it work with my circuit.

So I would like to knw how to make Curved arrows with label in the middle ?

How can I add $Z_c$ insde the generic component ?

How to box the Outside of the transformer ?

And finally, can I have multiple type of arrows in the same drawing, it look like if I change the european / american arrows, it change for all of them.

thanks

Curved arrows: Use \draw[->] (node1) edge [bend X=Y] (node2); where X can be left or right and Y gives the degree of bending. With the tikz library arrows you get a variety of arrows. By adding the option >=stealth' you get a particular type of arrow, shorten >=3pt tells to stop in a distance of 3pt before the destination.

Label inside the generic component: I add \hspace{-3.5cm} to the normal label that would otherwise be outside. Just a hack, but I found no other solution.

Box around transformer: \draw[dashed] (T) +(-1,-4.2) rectangle +(1,0.2); draws a dashed rectangle relative to node (T). Note that the single + does not change the position, hence the opposing corners of the rectangle are (T)+(-1,-4.2) and (T)+(1,0.2).

Multiple types of arrows: I'm not completely sure what you mean. You now have already two types of arrows. Maybe ask another question with a more precise description.

Addendum: To magnify components, use the /tikz/circuitikz/bipoles/length option, like that:

node[transformer, anchor=A1,yscale=1.9,/tikz/circuitikz/bipoles/length=2.5cm] (T) {}
[L,l={X$_{eq}$},/tikz/circuitikz/bipoles/length=2.5cm]

In the circuitikz components you can shorten the key to bipoles/length, in the tikz elements to circuitikz/bipoles/length, resulting in

node[transformer, anchor=A1,yscale=1.9,circuitikz/bipoles/length=2.5cm] (T) {}
[L,l={X$_{eq}$},bipoles/length=2.5cm]
