What is the formula of resistivity |
| Answer» Resistivity or specific resistance is resistance of a conducting material of unit length and having unit area of cross section. It is a property of material and depends on nature of material.ρ = RA/lWhere,\xa0ρ\xa0is the resistivity,\xa0R\xa0is the resistance,\xa0l\xa0is the length of the material and\xa0A\xa0is the area of cross-section.SI unit is Ohm-m (Ω.m) | |
