What is Resistance? Resistivity (ρ) & Specific Resistance Ω.
The resistivity is a fundamental property of a material that shows its strength of opposition to the current flow. It is denoted by Greek letter ρ (Rho). It is a constant value & different materials have different resistivity. It is derived from resistance; R = ρ l/A. ρ = R A/l. ρ = Ω-m (Ohm-meter)

ρ (Rho) - (College Physics I – Introduction) - Fiveable
ρ, or rho, is a symbol commonly used in physics and mathematics to represent various physical quantities, including density, resistivity, and the Stefan-Boltzmann constant. This versatile symbol is particularly relevant in the contexts of fluid mechanics, wave theory, and electromagnetism.
What is Electrical Resistivity? - Electronics Area
The resistivity [ρ] (rho) has the formula: ρ = R*A/L. Where: A is the cross-sectional area (m 2). ρ is the resistivity, (ohms-meter). L is the length of the material (meters). R is the value of the electrical resistance (ohms).
