这个特定电压源的 tikz 代码是什么？

Question

我正在使用 circuitikz，但找不到此特定电压源的代码。它是一个正弦电源，其两端的极性为 + 和 -，位于圆圈内。

Answer 1

下面定义了一个新的符号，circuitikz称为sVpm（对于負責 页lus 和米您可以在电路内部使用 （即 inus）。它只是 定义的副本sinusoidal voltage source与 的定义相结合american voltage source，并对一些参数进行了略微调整。

它还提供了一种用于水平输出的变体，称为sVpmh。

编辑另一种水平变体不仅可以转动减号，还可以旋转正弦波并进行一些空间和尺寸调整：
