How to Calculate Series and Parallel Resistance
What it is.
Step-by-Step Guide

Step 1: What it is.
Series resistance is simply connecting the "out" side of one resistor to the "in" side of another in a circuit.
Each additional resistor placed in a circuit adds to the total resistance of that circuit.
The formula for calculating a total of n number of resistors wired in series is:
Req = R1 + R2 + ....
Rn That is, all the series resistor values are simply added.
For example, consider finding the equivalent resistance in the image below In this example, R1 = 100 Ω and R2 = 300Ω are wired in series.
Req = 100 Ω + 300 Ω = 400 Ω
