How the calculation works
Add resistor values connected in series and calculate total resistance. The tool converts the form units and presents the result using readable engineering notation.
Rₜ = R₁ + R₂ + …
Example
100 Ω + 220 Ω + 1 kΩ = 1.32 kΩ.
How to interpret the result
- A series connection raises total resistance and splits voltage across parts.
- The same current flows through every resistor, so calculate each power loss separately.
- Worst-case tolerances can accumulate and shift the final value.
Limitations and safe use
The result uses a simplified model. Check tolerance, temperature, absolute ratings and the component datasheet.
FAQ
Is the result saved?
The latest result may be stored locally in this browser, but it is not sent to LutujTo.
Can I use the result in a project?
Yes, but select a real component with margin and confirm its ratings in the datasheet.
