If you don't have to use circuitikz
, I can recommend the following (which is a modified version of a transformer that Thomas Söll drew and posted here):

Sorry. I copied the code with "scope" from here. Then I realized the word "transform shape". Then I tried it as direct argument and it worked.
Code:
\documentclass{standalone}
\usepackage[utf8]{inputenc}
\usepackage[siunitx]{circuitikz}
\begin{document}
\begin{circuitikz}
\draw
(0,0) node [transformer](t1){}
(0,-3.5) node [transformer, rotate = 30](t2){}
(3.5,-1.75) node [transformer, rotate = 30, transform shape](t3){}
;
\draw
(t1.B1) to [R]
++(right:2)
(t2.B1) to [R]
++(right:2)
(t3.B1) to [R]
++(right:2)
;
\end{circuitikz}
\end{document}
output:

Best Answer
The number of coils can be configured, also within a picture:
