尝试使用 Circuitikz 创建简单电路

Question

我正在尝试使用该包创建图中所示的电路circuitikz，但我找不到任何类似的示例来以这种方式排列元件。有人能帮我提供代码吗？

Answer 1

因为这是一个需要我亲自做的问题，所以这对我来说只是一次练习，我不会再回答与此相关的其他问题。

\documentclass{article}
\usepackage[dvipsnames]{xcolor}
\usepackage[american,siunitx]{circuitikz}
\usetikzlibrary{arrows.meta}

\ctikzset{current arrow color/.initial=black}% create key
\pgfdeclareshape{currarrow}{

        \pgfpointorigin
    }
    \anchor{tip}{
        \pgfpointorigin
        \pgf@circ@res@step = \pgf@circ@Rlen
        \divide \pgf@circ@res@step by 16
        \pgf@x  =\pgf@circ@res@step
    }
    \behindforegroundpath{      

        \pgfscope
        \pgf@circ@res@step = \pgf@circ@Rlen
        \divide \pgf@circ@res@step by 16

        \pgfpathmoveto{\pgfpoint{-.7\pgf@circ@res@step}{0pt}}
        \pgfpathlineto{\pgfpoint{-.7\pgf@circ@res@step}{-.8\pgf@circ@res@step}}
        \pgfpathlineto{\pgfpoint{1\pgf@circ@res@step}{0pt}}
        \pgfpathlineto{\pgfpoint{-.7\pgf@circ@res@step}{.8\pgf@circ@res@step}}
        \pgfpathlineto{\pgfpoint{-.7\pgf@circ@res@step}{0pt}}           
        \pgfsetcolor{\pgfkeysvalueof{/tikz/circuitikz/current arrow color}}
        \pgfusepath{fill,draw}
        \endpgfscope
    }
}
