The Resistance of a Conductor of Length X is R. If Its Area of Crosssection is A, What is Its Resistivity? What is Its Unit? - Science and Technology
The resistance of a conductor of length x is r. If its area of crosssection is a, what is its resistivity? What is its unit?
Resistivity of a conductor, `ρ = RA/L`
Here, L = x, R = r and A = a
`therefore ρ = ra/x`
The unit of resistivity is ohm-metre (Ω m).
