电压源对角连接时负极性符号的方向

跟进的这问题。MWE 如下：

\draw ($(a)+(0.0,0.0)$) node[circ]{}  to [cV, l=1<\volt>] ($(a)+(0.0,1.0)$) node[circ]{}

输出结果为

tikz+circuitikz 的默认输出

当取消注释上述 MWE 中的代码时，输​​出为：

修改了水平显示的极性符号

然而，我也在寻找下面类似这样的东西，用于对角连接的电压源：

期望输出

请问有什么建议吗？

答案1

声明一个新变量bipoles/vsources/minus/sign/rotation/.initial=0，然后将其插入到组件重新定义中，vsourceAM并cvsourceAM在减号代码中旋转文本rotatebox:

... \pgftext[options]{\rotatebox{bipoles/vsources/minus/sign/rotation}{$-$}}

要启用旋转减号的选项，请在组件定义中将值更改为 90 度：

...
to [V,l_=$2V$,-*,bipoles/vsources/minus/sign/rotation=90] 
...

这里 MWE 使用为 circuitikz 定义的语法和相对坐标++(x_shift,y_shift)，在这种情况下取​​决于的值\dist，着手4cm使用 获得更好的表示bipoles/length=2cm，请注意，要绘制短裤，使用符号*-，-*而*-*不是绘制圆圈；要更改大小，要更改的值为：nodes width/.initial=0.03。

结果：2V 对角线控制源有符号修改，4V 对角线独立源为默认值 0。您可以选择看起来更好的。
