Problem 13.10
Wow, I am surprised that the total relative loss due to the proximity effect is nearly 100! That last secondary layer, at least in my calculations, really takes a beating.
Did you mean relative to (I)^2*Rdc or the total loss at dc?
I am not sure, but if I did it right, I get a lower value as compared to the total loss at dc (although it is still higher, and perhaps the problem tries to demonstrates that), but I do get it close to 100 if I compare to just I^2*Rdc.

On a second thought, I might not have done it right. I am checking my calculations again.
