Rearrange resistivity equation
WebbFrom this equation, I can see that the resistivity will be the resistance over length multiplied by the cross-sectional area. I rearranged the equation and substituted into the straight line equation as is shown below. y = mx + c. R = ρL / A R ∝ L . The value of resistance of the material is depends on the value of the length.
