The electrical resistivity of a material is defined as the resistance of a conductor made of that material of unit length and unit cross-sectional area. Its Sl unit is Ohm metre ..
•Resistivity :- Resistance depends upon resistivity which is a proportionality constant and depends on nature of substance and temperature.
•Temperature :- As the temperature increases, the value of resistivity increases so resistance increases . .
•Length :- Resistance is directly proportional to the length ......
