Series to Parallel Conversion
Convert a series connected impedance and reactance into a parallel circuit or vice versa.

R = | ≈ | Ω | ||
X = | ≈ | Ω |
Please note that approximations are valid if Rs2 << |Xs|2 or Rp2 >> |Xp|2 .
Fill out the fields, you can use SI suffixes in your numbers e.g. 10k would be 10 kilo. Capitalization matters, as 1m would be 1 milli and 1M would be 1 mega. Finally, press the "Convert" button to get the answer.
Description:
In some cases it is convenient to deal with series circuits, in some other - with parallel. Series-to-Parallel Conversion allows to transform one circuit into another one keeping the total impedance of the circuit constant.
Series to parallel conversion.
The circuits are interchangeable if
- for series to parallel conversion Rp= (Rs2 + Xs2) / Rs ≈ Xs2 / Rs , and Xp= (Rs2 + Xs2) / Xs ≈ Xs ,
- for parallel to series conversion Rs= Rp·Xp2 / (Rp2 + Xp2) ≈ Xp2 / Rp , and Xs= Xp·Rp2 / (Rp2 + Xp2) ≈ Xs
Remember, that the approximations are valid only if Rs2 << |Xs|2 or Rp2 >> |Xp|2 .
