Question #7cead

Answer 1

We all know that `R=rho**L//A`

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