我是 Circuitikz 的新手。因此,我需要一些帮助来绘制实验报告的小电路。如果有人能帮助我,我将不胜感激。这是电路:
我成功地做到了这一点:
\begin{circuitikz}
% Variable Voltage Source
\draw (0,0) to[american voltage source, v=$V_s$] (0,3);
% Draw node
\node at (1,3) [circle, draw, fill=black, inner sep=0pt, minimum size=3pt] {};
% Connect to node
\draw (0,3) to[short] (1,3);
% Open circuit
\draw (1,4) -- (2,3) to[short, *-*] (2,3);
% Ammeter
\draw (2,3) -- (2.5,3) to[ammeter, l=A] (4,3) -- (5,3);
\draw (5,3) -- (5,0);
\draw (0,0) to[short] (0,-2);
\draw (0,-2) to[voltmeter] (5,-2);
\draw (5,0) to[short] (5,-2);
\draw (0,0) to[lamp, *-*] (5,0);
\end{circuitikz}
输出结果如下:
这样可以吗?或者可以改进吗?
答案1
我会使用这个代码:如果您阅读手册教程部分中的示例,您将看到使用相对坐标、命名坐标和垂直“技巧”的优势-|
。|-
\documentclass[border=2mm]{standalone}
% always select a type of voltage orientation
\usepackage[RPvoltages]{circuitikz}
\begin{document}
\begin{circuitikz}
% Variable Voltage Source
% you are using an american symbol with european (arrow) voltage notation, without
% specifying a direction style. Avoid the horrible double marking of the voltage
% better use relative movements, name the generator for future reference
\draw (0,0) coordinate(start)
to[american voltage source, l=$V_s$, name=vv] ++(0,2)
% continue the drawing with the switch:
|- ++(1,1) to[nos=L, *-*] ++(1,0)
% Ammeter: the newer rmeterwa symbol is, in my opinion, better
to[rmeterwa, t=A] ++(3,0)
% move to the same vertical position than start
coordinate(upper left) -- (upper left |- start)
% close with the lamp
coordinate(start lamp) to [lamp, *-*] (start);
% using one path gives better "corner" junctions, as above.
% now add the voltmeter
\draw (start) -- ++(0,-2) coordinate(start v)
to[rmeterwa, t=V] (start v -| start lamp) -- (start lamp);
% add a tunable arrow to the generator, to show it's variable
\ctikztunablearrow[color=gray]{2}{1.2}{-30}{vv}
\end{circuitikz}
\end{document}
电路中的所有数字都是相对的,然后使用命名坐标进行连接。因此,如果您认为绘图太宽,您可以将++(3,0)
安培表的更改++(2,0)
为:
无需触碰代码的任何其他部分。
