Answer:
Resistance is the property of a conductor to resist the flow of charges through it.
Resistance is the obstruction offered to the flow of current by a conductor.resistance depends upon the properties of the object.
Resistivity is the electrical resistance per unit length and per unit of cross-sectional area.
resistivity depends upon the properties of the metal.
