How to fill it
Add rows as you need them. The tool uses every row you enter.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.
Formula

Diagnose
This tool does not attach diagnose observations.
Assumptions
- Resistances are non-negative. A zero-ohm branch shorts the combination.
Provenance
- General electrical engineering relationship.
