Impedances in series and in parallel: Changed "any" to "some." A simple counterexample is a tetrahedral network of resistors. Any two terminal network of impedances can be reduced to a single impedance with the methods mentioned later in this article (please find a citation for this), but not by simple series and parallel transforms.

===Impedances in series and in parallel===
AnySome two terminal network of impedances can eventually be reduced to a single impedance by successive applications of impedances in series or impedances in parallel.
