Coursework - Determining Resistivity

[coolnufc]

Hi guys, I am trying to work out ρ in an experiment.

Ive got down to ρ/AxV = 6.4
I know V = 2 and A=0.0907mm, but it should be m.

If i then work it out i get a stupidly small answer. Anyone help me out. Its like 0.0016096

It was nichrome wire (28 swg) i was using if that helps

So, what's the problem?
What is A, x and V? Why should it be m?
What does 28swg mean?

I agree with Engineer -- you need to be much clearer in your question. It would have helped if you had used the Homework Help Template that you are provided when you start a new homework thread. Please try to re-phrase your question in the form of the template:
