Is this the correct diagram of finding equivalent impedance

Click For Summary
SUMMARY

The discussion centers on verifying the accuracy of a diagram related to finding equivalent impedance using delta-wye transformation. The participant questions whether the top node labeled "a" should be split into -j5 and j2 before proceeding with the transformation of the other nodes. This indicates a need for clarity in the application of the delta-wye transformation method in circuit analysis.

I am still trying to figure out which node you are trying to simplify. If you are doing delta-wye transform shouldn't the top node " a " be spliting into -j5 and j2 and then you do a transform of the others.
