Question

what is resistivity state its symbol and its formula​

Answer 1

Explanation:

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. The unit of resistance is the ohm.

Answer 2

Answer:

Symbol of resistivity = ρ (rho)

and, its formulae is, ρ= (RA)÷L

(where R- resistance, A- area, L- length of conductor)
