Description
fraction = branchConductance/totalConductance; branchCurrent = totalCurrent*fraction.
Ideal electrical component relations assume a stated topology, fixed parameters and coherent units. A local voltage, current or transformation term can be algebraically valid without accounting for parasitics, ratings or safe practical connections.
fraction = branchConductance/totalConductance; branchCurrent = totalCurrent*fraction.
When to use this tool
Use Current Divider Conductance Fraction when checking one explicit ideal-component or divider relationship.
How to use the tool and how it works
- Enter totalCurrent, branchConductance, totalConductance. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read branchCurrent, fraction. Use the output convention below.
Require nonnegative branchConductance and positive totalConductance with branch <= total. fraction = branchConductance/totalConductance; branchCurrent = totalCurrent*fraction.1

| totalConductance | Total Conductance | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| branchCurrent | Branch Current | Required. Finite number. |
| fraction | Dimensionless fraction on the stated denominator basis, not multiplied by 100. | Required. Finite number. |

}Limitations and assumptions
- Conductances use one unit. The total is supplied, not reconstructed from a branch list, and signed current is a reference choice rather than a detected flow direction.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use a complete circuit model and qualified practical design when loading, nonlinearity, transients or safety limits matter.
