Question

the specific resistance per unit area of cross section of a wire is equivalent to​

Answer 1

Specific resistance means resistivity i.e ρ

we know that R = ρ $\dfrac{l}{A}$

According to the question:-

We need to find the value of $\dfrac{ρ}{A}$

R = $\dfrac{ρ}{A}$ × l

$\dfrac{R}{l}$ = $\dfrac{ρ}{A}$

hence, our answer is Resistance/ length
