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?

First convert the delta connected Zl to star connected impedance. The source is star connected. Once you find star equivalent of Zl you can add Zl and (1+j2)
