Shunt Current
Current from measured shunt voltage and known shunt resistance.
Current from measured shunt voltage and known shunt resistance.
App id: SHUNT-01. 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
I = Vsh / RshInputs
| Name | Unit |
|---|---|
| Shunt resistance | ohm |
| Shunt voltage (camera) | mV |
Outputs
| Name | Unit |
|---|---|
| Current (hero result) | A |
Diagnose
Observations are context. They do not pass or fail a structure. See Diagnose.
| When | Observation | Severity |
|---|---|---|
Current = 0 | Zero current | caution |
Current < 0 | Negative current | caution |
Assumptions
- Direct current. Shunt resistance is known and positive.
Provenance
- CP4 exam preparation material documents shunt/current relationships; independently verify against an authoritative CP training reference before release.
