Formula and methodology
Formula: I1 = Itotal R2 / (R1 + R2); I2 = Itotal R1 / (R1 + R2).
A two-branch current divider assigns more current to the lower-resistance branch while conserving the entered total current. This page reports branch magnitudes only.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Total current — A; minimum 0; maximum 1000000000
- Branch 1 resistance — ohm; minimum 1.0E-12; maximum 1000000000
- Branch 2 resistance — ohm; minimum 1.0E-12; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Total current | 3 |
| Branch 1 resistance | 2 |
| Branch 2 resistance | 4 |
Branch currents are 2 A in branch 1 and 1 A in branch 2.
Assumptions and limits
- The two branches are ideal resistors connected in parallel.
- Resistances are positive and entered in ohms; total current is a nonnegative magnitude.
- Source impedance, resistor heating, frequency dependence, and branch reactance are not modeled.
