Hi Guys, I have a question thats bugging me, if you can help. I need to calculate Is when I1 = 4 + j10 Z1= 9+J10 Z2=2 + j6. Is= I1x Z1/Z1 + Z2. Is this just multiplying by the complex conjugate? Would I just do (9 +j10) (9 +j10 + 2 + j6) = (9 +j10) x (11 - j16) (11 +j16) (11 - j16 Then multiply the answer by I1 which would be 4? Thanks Guys.
