Resistivity =The formula for resistivity is: $\frac{RA}{L}$, where$$\rho = \frac{RA}{L}$$ where $R = \text{Resistance}$$\rho$ is resistivity, $R$ is resistance, $A = \text{Area of cross section}$$A$ is cross-sectional area, and $L = \text{length of conductor}$$L$ is the length of the conductor. So we
We can see from the formula that $A$ and $L$ are involved. Then, why then does resistivity not depend on dimensions?
