I think is an author's preference thing John. Either way it should be the same result, I think.Can someone explain why their formula page 73, for VR=Vfl-Vnl/Vnl, is opposite the EERM 40.11 which is Vnl-Vfl/Vfl?

They used the absolute value on Kaplan's. They change the order in the numerator on the equation and then change the denominator.I can't find this book - I must have given it away. It is probably a typo. THere may be some circumstances where these are equal, or the Kaplan formula is correct, but I would go with the formula from the EERM to be safe.
I think the important thing is that it seem like you have a good understanding of the problem, better than me at this point. You are well on your way to passing, I think.
John,I have seen your comments and Luis's about Kaplan, I do like they way they take you through stuff, but dammit it is filled with mistakes that I spend more time trying to understand if its a mistake or something I'm not getting. I cant afford the wasted time.

I wish I had the book still so I could help. The truth is there is nothing magical about Kaplan - it is just a more challenging practice test than the "the other board" tests. But if you feel it is frustrating you and wasting your time there is no reason to force yourself to use it. The only really critical practice exam, IMO, is the NCEES practice test. Every person is different, and as a person who has recommended this Kaplan test on the board, I didn't want to give the impression that it was an irreplaceable reference. Just one of the few practice tests around,Well I don't know about that, but I again thank you for your vote of confidence.

Another on problem 1.35 solution page 74 wtf is 227.962? should be 277.962 and yield an answer of 28.66/_-41.14 Amps? Regardless where does this formula come from?

Oh youre right Benbo, and you DO help. Thanks for that. I am going to concentrate these last day working PPIs and NCEES exams. I will need your help on the ECC stuff. My fear now is i didnt spend enough time on all that. I feel a little better on the power stuff.I wish I had the book still so I could help.
