• Moved from another forum, so homework template missing
Hello
In this problem I tried to find the voltage at 2Z0 (load) that is (landa/4) from generator.My result it is different from teacher's result.what is my mistake?
(I named V1e as A point and V2e as B point so the voltage across the B point is (Vs/4) according to Zin=Z0 that is the same as Z0 of generator's impedance)

my solution:

Any helo would appreciate

looks like homework, should have been in that section

Why does it say "√2Z0" in the middle of the line? The chas. impedance of the line is by definition Z0.
So change your source impedance to Z0/√2 and your load impedance to √2Z0 or you're going to get mighty messed up.

Dear rude-man
Thank you for accompanying me
In this problem it assumes that Zc=√2 Z0 it means that the characteristic impedance of line is Zc not Z0 and the other values are Z0 and 2Z0 they don't need to be changed
