Vedclass · Answer

(A) The resistance of a material depends on its resistivity $(\rho)$.Rubber is an insulator, meaning it has a very high resistivity, which prevents the flow of electric current.Copper is a conductor, meaning it has a very low resistivity, which allows electric current to flow easily.Since resistance $R = \rho \frac{l}{A}$, for pieces of the same dimensions (length $l$ and area $A$), the material with higher resistivity will have higher resistance.Therefore, the resistance of rubber is significantly higher than that of copper.

The resistance of a piece of rubber is higher than that of a piece of copper of the same dimensions.
