Answer / Dharmendra Kumar Mourya

Resistivity (ρ) is a fundamental property of a material that quantifies its electrical resistance per unit length and cross-sectional area. To find the resistivity of a material, you need to measure the resistance (R) of a specimen with known geometry (length L and cross-sectional area A). The resistivity can then be calculated using Ohm's law: ρ = R * (A / L).
