Question

What is the difference between resistance and resistivity?

Answer 1

Definition

1. The opposition that material provides to the passage of electric electricity is called resistance.
2. Resistivity is a physical characteristic of a specific material with certain dimensions.

Difference between resistance and resistivity

Parameter	Resistance	Resistivity
Definition	The property of a material that obstructs the flow of current.	Material resistance with particular dimensions.
Symbol	R	$\mathrm{\rho }$
SI Unit	$\mathrm{Ohms}$	$\mathrm{Ohms}-\mathrm{meter}$
Formula	$\mathrm{R}=\frac{\mathrm{V}}{\mathrm{I}}$ or, $\mathrm{R}=\mathrm{\rho }\left(\frac{\mathrm{L}}{\mathrm{A}}\right)$ Here, V is the voltage, I is the current, and ρ is the resistivity.	$\mathrm{\rho }=\frac{\left(\mathrm{R}\times \mathrm{A}\right)}{\mathrm{L}}$ Here, R is the resistance, L is the length, and A is the cross-sectional area
Dependence	Temperature, Length, and Cross-sectional area	Temperature

Therefore, the movement of free electrons would be a significant distinction between resistance and resistivity.
