DC Fundamentals Unit 9 – Series/Parallel Resistive Circuits
UNIT 9 – SERIES/PARALLEL RESISTIVE CIRCUITS
UNIT OBJECTIVE
At the completion of this unit, you will be able to find values for resistance, voltage, and current
in a series/parallel resistive circuit.
UNIT FUNDAMENTALS
The rules for evaluating resistance, voltage, and current in a series/parallel circuit are a
combination of the rules you used to evaluate series and parallel circuits.
A series/parallel circuit is shown. R1 is the series element of the circuit; R2 and R3 are the
parallel elements (RE). RT is the combined resistance of R1, R2, and R3.
R1: series element
R2 and R3: parallel elements
RE: combined R2 and R3 value
RT: combined R1 and RE value
