[Tex/LaTex] circuitikz rotate transformer

circuitikz

Is it possible to rotate transformer without using scope?
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){}
        ;
        \begin{scope}[shift = {(3.5,-1.75)}, rotate=30, transform shape]
            \draw
                (0,0) node [transformer](t3){}
            ;
        \end{scope}
        \draw
            (t1.B1) to [R]
            ++(right:2)
            (t2.B1) to [R]
            ++(right:2)
            (t3.B1) to [R]
            ++(right:2)
        ;
    \end{circuitikz}
\end{document}

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}

[Tex/LaTex] Rotate voltmeter CircuiTikz

I see that in the last version of circuitikz, the definitions for ammeter and voltmeter have been changed, so if your version is 0.3.0 or newer, use the following code. If you don't need the diagonal arrow, comment the last two \pgfusepath{draw}. However I notice that now the circles don't touch the wires (I wonder why). If you want to correct this behaviour, replace the lines

\pgfpathcircle{\pgfpointorigin}{.9\pgf@circ@res@up}
<...>
\pgfpathlineto{\pgfpoint{-\pgf@circ@res@other}{\pgf@circ@res@up}}

with

\pgfpathcircle{\pgfpointorigin}{\pgf@circ@res@up}
<...>
\pgfpathlineto{\pgfpoint{-1.06\pgf@circ@res@other}{1.06\pgf@circ@res@up}}

but then you have to do the same in the ammeter definition. enter image description here

\documentclass{standalone}
\usepackage{circuitikz}
\makeatletter
\def\pgf@circ@myvoltmeter@path#1{\pgf@circ@bipole@path{myvoltmeter}{#1}}

                               path=\pgf@circ@myvoltmeter@path}}
\pgfcircdeclarebipole{}{\ctikzvalof{bipoles/voltmeter/height}}{myvoltmeter}{\ctikzvalof{bipoles/voltmeter/height}}{\ctikzvalof{bipoles/voltmeter/width}}{

    \else
        \def\pgf@circ@temp{below}
        \ifx\tikz@res@label@pos\pgf@circ@temp

    \fi

    \pgfpathmoveto{\pgfpoint{\pgf@circ@res@left}{\pgf@circ@res@zero}}       
    \pgfpointorigin \pgf@circ@res@other =  \pgf@x  \advance \pgf@circ@res@other by -\pgf@circ@res@up
    \pgfpathlineto{\pgfpoint{\pgf@circ@res@other}{\pgf@circ@res@zero}}

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):
