I would like to know how to scale a single component in CircuiTikZ.

There are several possibilities to scale paths, a hole diagram, etc., but I didn't find a way to do so with a single component.

Note: I'm trying to scale a voltage source.

I don't see an official way to do it, but it appears that all the lengths are based on /tikz/circuitikz/bipoles/length, so you can just change that. Here is the default size and scaled version in between:

enter image description here


\draw (0,0)
    to [sV=$a_1$] (2,0)
    to [C=$\SI{100}{\ohm}$](3,0)
    to [/tikz/circuitikz/bipoles/length=2.5cm,sV=$a_2$] (5,0)
    to [sV=$a_1$] (7,0);
  • I've tried this before and it works, but I was searching something like the 'scale' command. In the absence of a better solution I take this as the correct answer. For further uses it could be complemented with a '\newcommand'.

  • This only applies to bipoles, not to other components like transistors.

    @JasonS - Actually, circuitikz uses bipoles/length (\pgf@circ@Rlen) to scale every component. Jul 12, 2019 at 15:15
