Resistance - It is a measure of the opposition that a circuit (or an electrical element) offers to the flow of electric current.
Resistance of a conductor is directly proportional to its length and inversely proportional to its area of cross-section.
Unit of resistance is Ohm, Ω.
Resistivity - It is the measure of a material’s ability to oppose the flow of current.
It depends on the property of the material. Its value is constant for a particular range of temperature.
Unit of resistivity is Ohm meter, Ω m.
