Delta to Wye Conversion Calculator

Convert three delta resistors to their wye equivalents.

R_A (Ω) 10

R_B (Ω) 10

R_C (Ω) 10

Formula: R_A = (R_AB·R_CA) ÷ (R_AB + R_BC + R_CA)

Step-by-step with your numbers:

1. Values used:

2. R_AB = 30 Ω

3. R_BC = 30 Ω

4. R_CA = 30 Ω

6. R_A = 10Ω

7. R_B = 10Ω

8. R_C = 10Ω

Did we solve your problem today?

Delta-to-wye (Δ–Y) conversion simplifies three-terminal resistor networks.

The math behind it

Each wye resistor is the product of the two adjacent delta resistors divided by the sum of all three.

A balanced 30 Ω delta becomes a 10 Ω wye.

When is it useful?

To analyse bridge circuits and three-phase systems that aren't simple series/parallel.
