The superposition theorem for electrical circuits

AI Thread Summary
The discussion centers on the validity of the superposition theorem in electrical circuits containing only resistors, capacitors, and inductors with series-connected emf sources. The key argument for its fulfillment is that all circuit elements, including the sources, must exhibit linear behavior across their entire operational range. Participants are encouraged to explore specific proofs and resources that may clarify the theorem's applicability. The conversation emphasizes the importance of linearity in determining the theorem's relevance. Understanding these principles is crucial for analyzing circuit behavior effectively.

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?

It all hinges on the elements (incl. the sources) being linear over the whole range.
 
I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
