Engineering How to Calculate Equivalent Impedance for Delta to Star Connected Circuits?

AI Thread Summary
To calculate equivalent impedance for delta to star connected circuits, first convert the delta-connected impedance (Zl) to its star equivalent. The source is star connected, so the star equivalent of Zl must be determined before proceeding. The initial attempt to add (1 + j2) to Zl is not correct until the conversion is complete. After finding the star equivalent of Zl, it can then be added to (1 + j2) for the final equivalent impedance. Understanding the conversion process is essential for accurate calculations.

The Attempt at a Solution



Hey everyone, just having a problem in getting an equivalent circuit. I know how to do the problem, I am just confused on how to get a equivalent impedance:

I was doing (1 + j2) + (ZL) but I am not sure if that is correct?
