Homework Help: Coursework - Determining Resistivity

  1. Apr 21, 2009 #1
    Hi guys, im 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

    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:

    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
