我想要绘制一个具有电感耦合的电路，如下图所示：

在此处输入图片描述

我现在需要的是放置与电感耦合相关的点以及电源线。我认为如果它们是平的，我可以使用 TikZ 绘制这些点，但由于它们是波浪形的，我不知道该怎么做。

这是我到目前为止写的代码（我在两个耦合电感之间放了两行）：

\documentclass[border=2pt]{standalone}
\usepackage{circuitikz}

 \begin{document}
\begin{figure}
\centering
\begin{circuitikz}
  \draw (0,0) to [short,o-o] (8,0);
  \draw (0,1.5) to [short,o-] (3,1.5);
  \draw (5,1.5) to [short,-o] (8,1.5);
  \draw (3,1.5) to [inductor] (5,1.5);
  \draw (6,2.5) to [short] (5,2.5) to [inductor] (3,2.5) to [short] (2,2.5) to [short] (2,3.5) to [C] (6,3.5) to [short] (6,2.5);
  \draw (2,3.5) to [short] (2,4.5) to [inductor] (6,4.5) to [short] (6,3.5);
  \draw (2,4.5) to [short] (2,5.5) to [resistor] (6,5.5) to [short] (6,4.5);
  \draw[-] (3.5,1.95) -- (4.5,1.95) node{};
  \draw[-] (3.5,2.05) -- (4.5,2.05) node{};
\end{circuitikz} 
\end{figure}
\end{document}

我怎样才能完成这幅画？

谢谢。

要绘制“波浪”线，您可以使用库snake提供的线条图案decorations.pathmorphing。使用segment length和amplitude参数来获得所需的精确线条样式。

代码

\documentclass[border=2pt]{standalone}
\usepackage{circuitikz}
\usetikzlibrary{tikzmark,decorations.pathmorphing}

\begin{document}
\begin{circuitikz}
  \draw (0,0) to [short,o-o] (8,0);
  \draw (0,1.5) to [short,o-] (3,1.5);
  \draw (5,1.5) to [short,-o] (8,1.5);
  \draw (3,1.5) to [inductor] (5,1.5);
  \draw (6,2.5) to [short] (5,2.5) to [inductor] (3,2.5) to [short] (2,2.5) to [short] (2,3.5) to [C] (6,3.5) to [short] (6,2.5);
  \draw (2,3.5) to [short] (2,4.5) to [inductor] (6,4.5) to [short] (6,3.5);
  \draw (2,4.5) to [short] (2,5.5) to [resistor] (6,5.5) to [short] (6,4.5);
  \draw[-] (3.5,1.95) -- (4.5,1.95) node{};
  \draw[-] (3.5,2.05) -- (4.5,2.05) node{};

  % wavy lines
  \draw[->,decorate,decoration={snake,segment length=30pt,amplitude=4pt}](0,.75)--(2,.75);
  \draw[->,decorate,decoration={snake,segment length=30pt,amplitude=4pt}](6,.75)--(8,.75);
\end{circuitikz} 
\end{document}

您还可以使用 PSTricks：

\documentclass{article}

\usepackage{pst-circ,pst-plot}
\newcommand*\CurvedArrow[4]{
  \rput(#1,0){
    \psplot[algebraic]{0}{#2}{#3*sin(6*x)+#4}
    \psline{->}(#2,#4)(!#2 0.15 add #4)
  }
}

\begin{document}

\begin{pspicture}(-0.4,-0.1)(7.3,8.8)
  \wire[arrows=*-*](0,0)(7,0)
  \coil[arrows=*-*](0,2)(7,2){}
  \coil(6,3.5)(1,3.5){}
  \psline(2.5,2.75)(4.5,2.75)
  \capacitor[arrows=*-*](1,5)(6,5){$C$}
  \coil[arrows=*-*](1,6.5)(6,6.5){$L$}
  \resistor[dipolestyle=zigzag](1,8)(6,8){$R$}
  \wire(1,3.5)(1,8)
  \wire(6,3.5)(6,8)
  \psdots[dotsize=2pt](5.5,2.15)(5.5,3.65)
  \rput(6.2,2.15){$n$}
  \rput(6.2,3.65){$l$}
  \CurvedArrow{-0.4}{1.05}{0.2}{1}
  \CurvedArrow{6.1}{1.05}{0.2}{1}
\end{pspicture}

\end{document}

输出

它几乎肯定可以变得更简单，但这是我的第一次尝试。

对于电感器的耦合，我会这样做：

\documentclass{article}
\usepackage{circuitikz}
\begin{document}
\begin{circuitikz} \draw
    (0,0) node[transformer] (T) {}
    (T.A1) node[above] {A1}
    (T.B2) node[anchor=west] {B2}
    (T.A1) node[below right=2mm] {$\bullet$}
    (T.B2) node[above left=2mm] {$\bullet$}
    (T.A1) -| (-1.5,1) to[C] (-3,1) |- (T.A2)
;\end{circuitikz}
\end{document}
