Haven't they sorted out that book yet? It had these same problems in the 16th ed of it.
Post the question up then mate. Lets all have a look
Haven't they sorted out that book yet? It had these same problems in the 16th ed of it.
only ever tried that sudoku once. should be renamed sodit, cause that's what i said after 3 minutes. cannot do them, same with that rubik cube, had one when they first came out. it went over next door's fence.
Allright ppl,
I've bought this book and have stumbled working on exercise 2 p174 (if anyone has the book). In particular the completion of the test results for the given circuit, which is a 63m ground floor socket circuit consisting of 8 socklet outlets wired in 2.5/1.5 pvc twin and earth. 2.5 resistance is 7.41m and 1.5 resistance is 12.10m, giving total resistance of 19.51 per metre.
So
r1 = 63 * 7.41 / 1000 = 0.46
r2 = 63 * 12.10 /1000 = 0.76
rn = 63 * 7.41 / 1000 = 0.46
So I calculate R1 + R2 = 0.46 + 0.76 / 4 = 0.31
But the book says its 0.08?
it does have errors, but it's still a very good book. even the bible has errors. LOL. :bucktooth:
The book is a disgrace, full of errors Mainly on the calculations, it was updated to be 17th compliant and they updated all the errors also
Its not the Chris Kitcher book is it ?
As you will find quite a few errors which IMO keeps you on your toes as it shows you are getting a true understanding of what you are doing!
