# Delta – Y Transformation Calculator

The Y–Δ Transform, also known as "delta–star", and "delta–wye", is a mathematical process used in the field of electronic engineering to simplify complex resistor networks. This calculator allows one to transform a delta (Δ) network to a wye (Y), and wye (Y) to delta (Δ) network, thus solving for unknown resistor values.

Enter the values of R1, R2, R3 of a delta resistor network to calculate the values of R4, R5, and R6 in an equivalent wye resistor network.

## Y – Delta Conversion

Enter the values R4, R5, R6 of a wye resistor network to calculate the values of R1, R2, and R3 in an equivalent delta network.

Input Y Network Resistor Values
R4:

R5:

R6:

R1:

R2:

R3:

I usually did this in my head and did not even require the node positions, however if you need to memorise the Δ -Y transformation formulas then there are some simple patterns in the numerator and denominator that could help make it easier.
