Delta to Wye/Star Conversion Calculator

where,

 R_a, R_b, R_c are the delta connected resistances as mentioned in the figure

 R₁, R₂, R₃ are the star connected resistances as mentioned in the figure

A three-terminal electrical network comprises of a star or delta resistor network. Resistances in such a network are neither parallel nor series. Because of this, using series and parallel circuit transformation methods would not directly simplify it. A mathematical method that streamlines these networks is the transformation from Delta to Star or Star to Delta. So, a star network is converted into delta and vice & versa for ease of circuit resolution which can be done with the help of this calculator.

Simply enter the delta network resistance values in this calculator to convert the resistance values to its star network resistance equivalent.
