当前在被动元素（或通用元素）旁边，而不是之前或之后

Question

我想在乳胶中绘制以下电路

我可以得到以下信息：

这很完美，只是我希望当前符号和标签位于通用元素的顶部/底部或左侧/右侧，而不是之前或之后（我目前以此结束 p）。有没有简单的方法可以实现这一点？我的代码是：

\documentclass{article}
\usepackage[siunitx]{circuitikz}

\tikzset{
    generic/.append style={color=cyan},
    cute inductor/.append style={color=cyan},
    I/.append style={color=red},
    V/.append style={color=red},
}

\begin{document}
    
\begin{figure}
\centering
\begin{circuitikz}[american,scale=.8]
    \ctikzset{resistors/scale=0.8, sources/scale=.8}
    \draw (0,0)
    to [V, l=9<\volt>,invert]           ++(0,3)
    to [generic, f<=$ i_1 $]    ++(3,0)
    to [short]                  ++(3,0)
    to [I,l=0.5<\ampere>,invert]        ++(3,0)
    to [generic,f>=$ i_4 $]     ++(0,-3)
    to (0,0)
    %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
    (3,3) to [generic,v<=$ v_2 $,*-*]   ++(0,-3)
    (6,3) to [generic,v>=$ v_3 $,*-*]   ++(0,-3)
 ;
\end{circuitikz}
\caption{PSC 1}
\end{figure}

\end{document}

该解决方案不是尝试改变 circuitikz 定位当前箭头的方式（已经做过，不好玩），而是覆盖open组件的当前箭头，并进行一些调整以纠正偏移量。

\documentclass{standalone}
\usepackage[siunitx]{circuitikz}

\tikzset{
    generic/.append style={color=cyan},
    cute inductor/.append style={color=cyan},
    I/.append style={color=red},
    V/.append style={color=red},
}
\begin{document}
\begin{circuitikz}[american,scale=.8]
    \ctikzset{resistors/scale=0.8, sources/scale=.8}
    \draw (0,0)
    to [V, l=9<\volt>,invert]           ++(0,3)
    to [generic, name=A]    ++(3,0)
    to [short]                  ++(3,0)
    to [I,l=0.5<\ampere>,invert]        ++(3,0)
    to [generic,name=B]     ++(0,-3)
    to (0,0)
    %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
    (3,3) to [generic,v<=$ v_2 $,*-*]   ++(0,-3)
    (6,3) to [generic,v>=$ v_3 $,*-*]   ++(0,-3)
 ;
\draw ($(A.west)+(-0.4cm,4pt)$) to[open, f=$ i_1 $] ($(A.east)+(-0.4cm,4pt)$)
      ($(B.west)+(4pt,0.4cm)$) to[open, f=$ i_4 $] ($(B.east)+(4pt,0.4cm)$);
\end{circuitikz}
\end{document}
