1. it all seemed pretty easy to start off with i've got all my results.
    Voltage against current with a variable thing. but i can't do the equation, i have drawen up the graphs and followed the formulas but the results all come out wrong.

    formulas: m=y/x m=volt/amp r=1/m which is the resistance
    resistivity= r=p*a/l p=r*l/a

    After competing these formulas the result comes out wrong HELP:frown:
