6-1: Finding RT for

Series-Parallel Resistances


Overview of Series-Parallel Circuits


A series-parallel circuit, or combination circuit,

combines both series and parallel connections.


Most electronic circuits fall into this category.

Series-parallel circuits are typically used when different

voltage and current values are required from the same

voltage source.


Series components form a series string.


Parallel components form a parallel bank.
