|The electrical resistance of an object is a measure of its opposition to the flow of electric current.||
Resistivity is the characteristic property of the material by which it resists the amount of current through it.
|It depends upon the length, area of cross-section and nature of the material of the given material, and physical conditions like temperature.||
It only depends upon the nature of the material and physical conditions like temperature.
|Its SI unit is ohm||Its SI unit is ohm meter.|
|It is denoted by R.||It is denoted by ρ (rho)|
