电路是tikz,定义了很多额外的形状。另一方面,to
不关注边缘,因此您必须指定锚点。
\documentclass[border=10pt]{standalone}
\usepackage{circuitikz}
\begin{document}
\begin{circuitikz}
\node[draw,circle] (A) at (4,4) {A};
\node[draw,circle] (B) at (8,3) {B};
\draw (4,3)
to[short] (A.south)
(A.west) to[R=$R_2$,v_>=$v_2$](0,4)
to[short](0,0)
to[battery=$V_S$](8,0)
to[short](B.south)
(B.west) to[R=$R_3$,v_>=$v_3$](4,3)
to[short](4,2)
to[R=$R_1$,v_>=$v_1$](0,2)
;
\end{circuitikz}
\end{document}
就我个人而言,我会选择:
\documentclass[border=10pt]{standalone}
\usepackage{circuitikz}
\begin{document}
\begin{circuitikz}
\draw (4,3)
to[short,-o] (4,4) node[above] {A}
to[R=$R_2$,v_>=$v_2$](0,4)
to[short](0,0)
to[battery=$V_S$](8,0)
to[short,-o](8,3) node[above] {B}
to[R=$R_3$,v_>=$v_3$](4,3)
to[short](4,2)
to[R=$R_1$,v_>=$v_1$](0,2)
;
\end{circuitikz}
\end{document}
