Resistivity coursework (HELP)

  1. Feb 18, 2004 #1
    Ok, the coursework i have been give is on the Resistivity of conducting putty. I know that Resistivity is the relationship between resistance, length and cross sectional area.
    But what do i do?

    Do i just get different lengths and thicknesses of a metal and find the resistance. Then work out the resistivity?

    Help i'm confused.

    Resistance (ohms)= Resistivity(ohmmetres) x Length (metres)
    Cross sectional area (metres squared)

    just rearrange the equation to find resistivity
