What is the difference between potential difference and resistivity

1.	What is the difference between potential difference and resistivity
Answer» Resistivity:\xa0The electrical resistivity is the electrical resistance per unit length and per unit of cross-sectional area at a specified temperature. The SI unit of electrical resistivity is the ohm⋅metre (Ω⋅m). It is commonly represented by the Greek letter ρ, rhoPotential Difference:\xa0The difference between the potential of positive and negative ions of current is called P.D
