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.

Draw the voltage source for a length that is equal to the diameter of the circle! And connect it separately.

For a controlled voltage source you could use

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:
