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?
[o)]
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
