How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.
Formula
Vdrop = I × RInputs
| Name | Unit |
|---|---|
| Current | A |
| Resistance | ohm |
Outputs
| Name | Unit |
|---|---|
| Voltage drop (hero result) | V |
Diagnose
This tool does not attach diagnose observations.
Assumptions
- Direct current. Resistance is non-negative. Signed current yields signed drop.
Provenance
- General electrical engineering relationship.
