Formula and methodology
Formula: Wye A=AB×CA/(AB+BC+CA); Wye B=AB×BC/sum; Wye C=BC×CA/sum.
The standard three-resistor network transformation reports each wye arm associated with its delta node.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Delta resistance AB — minimum 1.0E-6; maximum 1000000000000
- Delta resistance BC — minimum 1.0E-6; maximum 1000000000000
- Delta resistance CA — minimum 1.0E-6; maximum 1000000000000
Worked example
| Input | Value |
|---|---|
| Delta resistance AB | 6 |
| Delta resistance BC | 9 |
| Delta resistance CA | 12 |
Wye A=2.6667 Ω; Wye B=2 Ω; Wye C=4 Ω.
Assumptions and limits
- All three resistances are positive and use one resistance unit.
- The network is linear and the three terminals are labeled A, B, and C.
- Source impedance, parasitic elements, temperature drift, and frequency-dependent behavior are not modeled.
