我如何使用 circutikz 获取该图的 R？

Question

我正在尝试画这幅画

我试过

\documentclass[]{article}
\usepackage{circuitikz}
\usepackage[locale = DE]{siunitx}
\begin{document}
    \begin{tikzpicture}[c/.style={circle,fill,inner sep=1pt}]
    \draw (0,0) coordinate (A) to[R={$R$}] (3,0) coordinate (M) to[L, l={$L,r$}, inductors/width=1.4,inductors/coils=11] (6,0) to[variable capacitor,l={$C$}]  (8,0) coordinate (B);
    \path foreach \p/\g in {A/-90,M/-90,B/-90}{(\p)node[c]{}+(\g:3.5mm) node{$\p$}};
\end{tikzpicture}
\end{document}

并得到

我怎样才能获得第一张图片形式的R？

Answer 1

使用 europeanresistors 作为全局选项：

\documentclass[]{article}
\usepackage[europeanresistors]{circuitikz}
\usepackage[locale = DE]{siunitx}
\begin{document}
    \begin{tikzpicture}[c/.style={circle,fill,inner sep=1pt}]
        \draw (0,0) coordinate (A) to[R={$R$}] (3,0) coordinate (M) to[L, l={$L,r$}, inductors/width=1.4,inductors/coils=11] (6,0) to[variable      capacitor,l={$C$}]  (8,0) coordinate (B);
        \path foreach \p/\g in {A/-90,M/-90,B/-90}{(\p)node[c]{}+(\g:3.5mm) node{$\p$}};
    \end{tikzpicture}
\end{document}

对于单个电路：

\documentclass[]{article}
    \usepackage{circuitikz}
    \usepackage[locale = DE]{siunitx}
    \begin{document}
        \begin{tikzpicture}[c/.style={circle,fill,inner sep=1pt}, european resistors]
            \draw (0,0) coordinate (A) to[R={$R$}] (3,0) coordinate (M) to[L, l={$L,r$}, inductors/width=1.4,inductors/coils=11] (6,0) to[variable      capacitor,l={$C$}]  (8,0) coordinate (B);
            \path foreach \p/\g in {A/-90,M/-90,B/-90}{(\p)node[c]{}+(\g:3.5mm) node{$\p$}};
        \end{tikzpicture}
\end{document}

对于单个电阻器：

\documentclass[]{article}
    \usepackage{circuitikz}
    \usepackage[locale = DE]{siunitx}
    \begin{document}
        \begin{tikzpicture}[c/.style={circle,fill,inner sep=1pt}]
            \draw (0,0) coordinate (A) to[R={$R$}, european resistors] (3,0) coordinate (M) to[L, l={$L,r$}, inductors/width=1.4,inductors/coils=11] (6,0) to[variable      capacitor,l={$C$}]  (8,0) coordinate (B);
            \path foreach \p/\g in {A/-90,M/-90,B/-90}{(\p)node[c]{}+(\g:3.5mm) node{$\p$}};
        \end{tikzpicture}
\end{document}

Answer 2

@Edson 回答是正确的，但我忍不住要添加这个 --- 为什么不使用“极点”机制来添加点，而不是使用单独路径的复杂东西？

\documentclass[]{article}
\usepackage{circuitikz}
\ctikzset{european resistors}% preferred way to set global options, circuitkz has too many package options...
\usepackage[locale = DE]{siunitx}
\begin{document}
    \begin{tikzpicture}
         \draw (0,0) node[below]{$A$} to[R={$R$}, *-*] (3,0) node[below]{$M$}
              to[L, l={$L,r$}, inductors/width=1.4,inductors/coils=11] (6,0)
              to[variable capacitor,l={$C$}, -*]  (8,0) node[below]{$B$};
    \end{tikzpicture}
\end{document}
