Hey everyone, this is a problem straight from my book. It's an odd number, so the book has the answer in the back: 4.7 ohms
The setup is near impossible to explain, so I've attached a diagram of the setup. Basically, it is a circuit with some resistors (represented by squiggly lines) each with R=2.8 kilo-ohms.
I came up with:
[tex]R=(\frac{1}{3*2.8}+\frac{1}{2*2.8}+\frac{1}{2.8})^-1+2.8=4.33\Omega[/tex]
The -1 right after the frist parentheses is a ^-1, it's kind of hard to tell.
Did I do it wrong? Is the book wrong? Is it just a case where they rounded and I didnt?
