网格分析 LaTeX circuitikz

因此，我尝试创建一个非常简单的电路。这是我的代码：

\documentclass[border=10pt,multi,tikz]{standalone}
\usepackage{circuitikz,siunitx}% cfr: these seem necessary but what else?
\standaloneenv{circuitikz}
\begin{document}
\ctikzset{bipoles/resistor/height=0.15}
\ctikzset{bipoles/resistor/width=0.4}
\begin{circuitikz}
  \draw (0,0)
  to[I,i=$1 \mA$,] (0,5) % The voltage source
  to[short] (0,5)
  to[short] (4,5) % The resistor
  to[R=$ 1\kilo\ohm$,] (4,0) % The resistor
  to[short] (0,0);
  \draw (4,5)
  to[R=$1\kilo\ohm$] (8,5) % The resistor
  %to[short] (8,5)
  to[R=$10 \kilo\ohm$] (8,0) % The voltage source
  to[short] (0,0);
  \draw (8,5)
  to[R=$1 \kilo\ohm$] (14,5) % The voltage source
  to[R=$1 \kilo\ohm $]  (14,3)
  to[cV=$A V_{in} $]  (14,0)
  to[short] (0,0);
  \draw (10,5)
  to[short] (16,5) node[anchor=west]{A}
  to [open,o-o] (16,0)node[anchor=west]{B}
  to[short] (0,0);
  \draw [red,latex-] (2,2) node[above,color=red]{$i_2$} arc(-90:145:5mm)
\end{circuitikz}
\end{document}

我所要做的就是能够i_1, i_2,i_3在画出的细圆圈内写字，以表示流经整个网格的电流。

当我尝试放置圆形箭头时，出现错误。

答案1

我花了很多时间编译你的代码，所以现在我编译完代码后仍然不明白这个问题，这也许是意料之中的事。我不知道圆怎么会“细”。我以为你可能指的是椭圆，但似乎没有椭圆。

因此，也许您想将i_1和添加i_3到包含的圆圈中i_2。我想知道您是否想要额外的圆圈，但那没有意义。如果您知道如何制作一个，显然可以再制作两个。所以我只能认为问题是在同一个圆圈上添加额外的标签。

像这样：
