How to Calculate Resistors in Series
Calculate total resistance for resistors connected in series.
The Formula
R = R₁+R₂+R₃The resistors in series formula uses the mathematical relationship: R = R₁+R₂+R₃. Each variable in the formula represents a measurable quantity that affects the final result.
Step-by-Step Method
- 1Identify all input values needed for the resistors in series calculation.
- 2Substitute your known values into the formula: R = R₁+R₂+R₃.
- 3Perform the arithmetic operations in the correct order (PEMDAS/BODMAS).
- 4Check that your result has the correct units and is within a reasonable range.
- 5Verify using the interactive Resistors in Series to confirm your answer.
