Is the load impedance provided in the solution CORRECT?

Pls look at the Load Impedance calculation. The answer is given in the shaded (gray) box. Is the answer CORRECT? If YES, pls advise how to get it. The answer I got is ZL = 3.26 + j2.02. Pls advise. Thanks.

hi,
the answer in gray is correct. can you post your solution so that we can see what the difference is? or what is wrong..
thanks

Did u mean the answer for ZL in gray is CORRECT?

My calculation:

ZL
= V1 / I
= 240 / (53.1 - j32.9)
= 3.26 + j2.02

Pls advise.

hi
you are ok

 

[jeffttan]

your answer is correct... i think there was only an error in the conversion on the part of the author. the impedance in polar form obtained by the author when converted to rectangular form is the same as yours...

In your answer, it's 3.26 - j2.02. Why not 3.26 + j2.02? Thanks.
