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.
