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.
