Question

what is the resistivity area of wire formula?​

Answer 1

Answer:

Resistivity, commonly symbolized by the Greek letter rho, ρ, is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l; ρ = RA/l.

Good morning ✌

Answer 2

Answer:

Hi

Step-by-step explanation:

The resistance R of a cylinder of length L and cross-sectional area A is R=ρLA R = ρ L A , where ρ is the resistivity of the material. Values of ρ in Table 1 show that materials fall into three groups—conductors, semiconductors, and insulators
