如何在电路上放置颜色盒

Question

我想在某个东西周围放一个颜色框，基本上这次是一个电路，我还想放一根颜色更深的电线。这是我的代码：

\documentclass{article}
\usepackage[utf8]{inputenc} 
\usepackage{tikz}  
\usepackage{mathtools}  
\usepackage[american]{circuitikz}
\usetikzlibrary{shapes,arrows}  
\renewcommand*\contentsname{Contenido} 
\begin{document}

\begin{figure}[h]
\begin{circuitikz} 

%Diodo

    \draw 
    [short, o-] to (0.3,0)
    ;
    \ctikzset{bipoles/diode/height=0.4, bipoles/diode/width=0.4,} 
    \draw  
    (0.3,0)  node[below right = 4.15mm,align=center]{+} to[diode, a = $v_\gamma$, i = $i$]
  (3,0) node[below left = 4.15mm,align=center]{-} 
  ; 
  \draw 
  (3,0) [short,-o] to (3.2,0)
  ;  
  
 %Circuito abierto
  
\draw 
(5,0) [short, o-] to (6,0) 
to [-o,open] (8,0)  
; 
\draw 
(7.5,0) [short, o-] to (8.5,0)  
to [-o,open] (10.5,0) 
; 
\draw 
(5,0) node[above = 4mm, right = 1mm,align=center]{$\textcolor{red}{i}$ $\color{red}\longrightarrow$ } node[below = 10mm, right = 6mm,align=center]{$v<0\ $,  $i=0$} to [open, v =$v$ ] (8.5,0)
; 
%Corto circuito

\draw 
(10,0) [short, o-] to (11,0) 
to [-o,short] (13,0)  
; 
\draw 
(12.5,0) [short, o-] to (13.5,0)  
to [-o,short] (13.5,0) 
; 
\draw 
(10,0) node[above = 4mm, right = 1mm,align=center]{$i$ $\longrightarrow$ } node[below = 10mm, right = 6mm,align=center]{$i>0\ $,  $v=0$} to [open, v =$v$,red] (13.5,0)
; 


\end{circuitikz} 
\caption{Modelo Ideal}
\end{figure}  
\end{document}

这或多或少就是我所认为的样子。

我很感谢你的帮助！

在这里，我专注于添加背景矩形，而不是改进代码。我将许多事情保持得非常明确，以便更容易理解正在发生的事情。您的代码可以简化很多，而我的添加可以以牺牲可理解性为代价提高效率。

您可以命名一些坐标并将它们适合背景层上的矩形节点。

    \draw  
    (0.3,0)  node[below right = 4.15mm,align=center]{+} to[diode, a = $v_\gamma$, i = $i$]
  (3,0) node[below left = 4.15mm,align=center]{-}
