We all know that $R = ρ * L / A$ $R=rho**L//A$

And $ρ$ $rho$ is the property of the material.
That means $ρ$ $rho$ depends on the material used.
So by changing material you are actually changing its value of $ρ$ $rho$
This shows that increasing $ρ$ $rho$ of material increases Resistance.
But we all know that.
$V = I R$ $V=IR$
So $I \propto 1 / R$ $I prop 1//R$
So Increasing $ρ$ $rho$ will decrease $I$ $I$ (current)
We also know that increasing resistance decreases current.
