Hi fellow physicist!

I have some trouble with finding a valid argument, for why the superposition theorem should be fulfilled for electrical circuits - there only containing resistors, capacitors and inductors - where the sources of the emf. are connected in series.

Thanks in advance.

Have you found any valid arguments why superposition shouldn't be valid for such circuits?

Here is a proof. Maybe it will cover the case you are interested in.

It all hinges on the elements (incl. the sources) being linear over the whole range.
