Current density from current and exposed or active area.
Current density from current and exposed or active area.
App id: CUR-02. Reference version 1.0.
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
J = I / AInputs
| Name | Unit |
|---|---|
| Current | A |
| Area | m2 |
Outputs
| Name | Unit |
|---|---|
| Current density (hero result) | mA/m2 |
Diagnose
This tool does not attach diagnose observations.
Assumptions
- Area is the exposed or active surface the user intends.
- Signed current yields signed current density.
Provenance
- General current-density relationship J = I / A.
