## Homework Statement

The conductivity of a material depends on a) Resistance(R) b) Area of cross section(A) c) Length(L)

d) Resistivity(ρ)

## Homework Equations

## The Attempt at a Solution

The formula for Resistivity is given by ρ = AR/L and Conductivity(σ) being the reciprocal of Resistivity, the formula is σ = L/AR.

So, i think the answer is d) Resistivity since that term is missing in the given equation of conductivity. Am i inferring correct?

But at the same time, i also think in this way,i.e., if there is more resistance there won't be much conduction and less resistance means more conduction. So Conductivity also depends on Resistance.

Please help in this regard
