使用多行图例注释 tikzpicture 节点

我对 Tikz 还不是很熟悉。我想实现的是使用多行数学注释两个节点。
我正在处理下图：

我想用以下图例来代替注释：

这是我的 MWE。对我来说，这可能微不足道，但并不简单。任何帮助都将不胜感激。

您可以使用以下aligned环境：amsmath

$\begin{aligned}
  \mathrm{I_{\mathit{Nor}}} &= \SI{-0.2111-j0.5138}{\ampere} \\
                            &= abc
\end{aligned}$

请注意，如果您只想写一个单位，请使用\si{<unit>}而不是\SI{}{<unit>}。在这里，我将数字放在 的第一个参数中\SI。虽然默认输出与您的示例不相似，但您可以使用

\sisetup{
  multi-part-units=single,
  output-complex-root=\ensuremath{\mathrm{j}},
  complex-root-position=before-number
}

如果希望将此设置应用于整个文档，请将其添加到序言中，或者仅在之后\begin{tikzpicture}针对图表进行修改。

看起来circuitikz你的方案的绘制更简单：

\documentclass[border=5mm]{standalone}
\usepackage{steinmetz}
\usepackage{amsmath, amssymb}
\usepackage{siunitx}
\sisetup{
  multi-part-units=single,
  output-complex-root=\ensuremath{\mathrm{j}},
  complex-root-position=before-number
        }
\usepackage[siunitx]{circuitikz}

\begin{document}
\begin{circuitikz}[american]
\ctikzset{bipoles/length=9mm}
\draw (0,0)  to[isource, name=i,
                l=\footnotesize
               ${\begin{array}{r@{\,}l}
                I_{\text{Nor}}  & = \SI{0.130-j7.496}{\ohm}\\
                                & = 0.555\phase{-112.33}\,\si{\ampere}
                 \end{array}}$]   (0,2) 
             to[short, -*] (2,2) 
             to[short, -*] (5,2) node[right] {$A$}
       (2,2) to[R=\footnotesize
                ${\begin{array}{r@{\,}l}   
                Z_{\text{Nor}}  & = \SI{0.130-j7.496}{\ohm}\\
                                & = 7.497\phase{0.89}\,\si{\ohm}
                  \end{array}}$] (2,0) -- (0,0)
       (2,0) to[short,*-*] (5,0) node[right] {$B$};
\node[above right] at (i.east) {+};
\end{circuitikz}
\end{document}
