We all know that R=rho**L//AR=ρL/A

And rhoρ is the property of the material.
That means rhoρ depends on the material used.
So by changing material you are actually changing its value of rhoρ
This shows that increasing rhoρ of material increases Resistance.
But we all know that.
V=IRV=IR
So I prop 1//RI1/R
So Increasing rhoρ will decrease II(current)
We also know that increasing resistance decreases current.
