circuitikz 电压箭头离端子太近

Question

该代码在两个开放的终端上用箭头创建一个电压降：

\documentclass{article}

\usepackage[european,siunitx]{circuitikz}
\usetikzlibrary{arrows,calc,positioning}

\begin{document}
\pagenumbering{gobble} % Remove the page numbering

\ctikzset{bipoles/thickness=1}
\begin{circuitikz}[european, line width=0.8pt]
    \draw (0,0)
    to [short] (1,0)
    to [open, v^>=$v_{A}$, *-*, european voltages] (2,0)
    to [short] (3,0);
\end{circuitikz}
\end{document}

问题：箭头离端子太近。
如何将箭头向上抬起？

Answer 1

该open组件具有宽度和高度，但它太宽，无法放入给定的空间，从而扰乱电压程序。

\documentclass{standalone}
\usepackage[european,siunitx]{circuitikz}
%\usetikzlibrary{arrows,calc,positioning}

\begin{document}
%\pagenumbering{gobble} % Remove the page numbering

\ctikzset{bipoles/thickness=1}
\ctikzset{bipoles/open/width=.4}
\begin{circuitikz}[european, line width=0.8pt]
    \draw (0,0)
    to [short] (1,0)
    to [open, v^>=$v_{A}$, *-*,n=test] (2,0)
    to [short] (3,0);
   \draw[red] (test.ne) -- (test.nw) -- (test.sw) -- (test.se) -- cycle;
\end{circuitikz}
\end{document}
