Larry, this is basic electric circuit theory.? Any linear bilateral complex impedance can be expressed as an equivalent circuit of two components, a resistance and a reactance.? You can express them either as a series combination or as a parallel combination.? So all the parameters you mention are the results of that calculation.
A series combination is usually expressed as R + jX, and the R is called series R, or Rs.
???? And given the impedance in series format, it is possible to convert to an equivalent parallel circuit - and vice versa.? The equivalency will only be valid over a limited frequency range.
???? There are a lot of places on the web that can help you with this stuff.? For example, microwaves101.com.? Some specific pages, in no particular order:
???? Wikipedia also has some good stuff:
???? A good source of information on all things RF (Radio Frequency) is the ARRL Handbook for Radio Communications.
