Question

Why is rho the SI unit of both density and resistivity?​

Answer 1

Explanation: Density is an SI derived unit. It is derived from the SI fundamental unit for mass, the kilogram, and the SI fundamental unit for length, the meter. Density is the mass per unit of volume. ... So the derived SI unit for density is kgm3 .

Explanation :The SI unit of electrical resistivity is the ohm⋅metre (Ω⋅m). It is commonly represented by the Greek letter ρ, rho. Although the SI resistivity unit, the ohms metre is generally used, sometimes figures will be seen described in terms of ohms centimetres, Ω⋅cm.

Answer 2

Answer:

Rho is typically the symbol to define a volumetric density. The SI unit of that is kg/m3
