## Series Resistance Formula

The following equation is used to calculate the equivalent resistance of a set of resistors in series.

R = r1 + r2 + r3 … rx

- Where R is the equivalent resistance
- r1,r2, etc are the individual resistances of the components in series.

## Series Resistance Definition

Series resistance is defined as 2 or more components in a circuit that have resistance and are aligned in series.

## Series Resistance Example

How to calculate series resistance?

**First, determine the individual resistances.**Measure the individual resistances of each component.

**Next, determine the equivalent resistance.**Sum all of the resistances together to yield the equivalent resistance.

## FAQ

**What is a resistance?**

A resistance is a force against the flow of electricity. In other words, electronic components resist the flow of electricity.

**What is a series?**

A series is a type of electrical setup that has components in sequential order connected by one wire.
