Question

Derive the expression sigma = 1/rho.
(Sigma is conductivity; Rho is resistivity)​

Answer 1

Answer:

The resistivity formula can be represented as follows:

Resistivity = 1conductivity

The equation can be represented as :

ρ = 1σ

Here:

σ = conductivity

ρ = resistivity

Furthermore, another formula for resistivity can be

ρ = RAL

Here,

ρ = resistance

R = resistance

A = cross-sectional

L = length
