Electrical resistance is the hindrance to the flow of current. The unit of electrical resistance is ohm (Ω) which is defined as volt per ampere.
Resistivity is the measure of resistance of a given size of a specific material to electric conduction. The SI unit of electrical resistivity is ohm−metre (Ωm). It is commonly represented by the Greek letter ρ.
