Circuitikz 将文本放置在组件的上方和下方

Circuitikz 将文本放置在组件的上方和下方

假设我创建了一个这样的组件

(0,0) to [R, l^=$R1$] (0,2)

我怎样才能使得值 R1 位于右侧，而电阻（比如说 1kohm）位于左侧？

我试过了

(0,0) to [R, l^=$R1$, l_=$\SI{1}{\kilo\ohm}$] (0,2)

但这不起作用，因为它只是覆盖（或忽略）第一个 l^=...

谢谢。

编辑：添加了编译的示例代码和我想要的图片。

电路

答案1

电阻周围是锚点。您可以使用 n= 样式命名电阻节点，标签对面的锚点（通常）为“s”。

答案2

摘自手册版本 0.8.3（2017/05/28）第 34 页：“自版本 0.7 起，除了原有的标签 (l) 选项外，还有一个新选项，可以在每个双极子上放置第二个标签，称为注释 (a)。到目前为止，这是一个 beta 测试，可能会出现问题。”
