Combinação Série - Paralelo

Series-Parallel Combination

Most networks in AC circuits can be broken into blocks no more complicated than the one below. The complex impedance approach provides the tool necessary to reduce such a combination to an equivalent impedance. This kind of combination may be encountered in the development of an AC Thevenin equivalent for the analysis of an AC circuit.
Calculation
The parallel part of the impedance can be put in the form
which can be rationalized by the operation : ,
and when terms are collected the results can be added to Z1 , giving the equivalent
