Star (Y) Network Values

Star to Delta:
\( R_{ab} = \frac{R_a R_b + R_b R_c + R_c R_a}{R_c} \)
\( R_{bc} = \frac{R_a R_b + R_b R_c + R_c R_a}{R_a} \)
\( R_{ca} = \frac{R_a R_b + R_b R_c + R_c R_a}{R_b} \)

Delta to Star:
\( R_a = \frac{R_{ab} R_{ca}}{R_{ab} + R_{bc} + R_{ca}} \)
\( R_b = \frac{R_{ab} R_{bc}}{R_{ab} + R_{bc} + R_{ca}} \)
\( R_c = \frac{R_{bc} R_{ca}}{R_{ab} + R_{bc} + R_{ca}} \)
