Hi,

In Delta to Wye conversion, we obtain the resistance for the Wye network from node A to node B as R(AB) = R_A + R_B. But from my understanding R_A and R_B would not be connected in series since the middle node is also connected to R_C. So why are we allowed to obtain R(AB) = R_A + R_B?

Maybe I need clarification of what a series circuit is.

Thank you for the help.

You are doing it wrong.
