what are the factors on which resistivity of a conductor depends
parneet43:
length - resistivity depends on the length .if lengt is doubled resistivity als doubled because resistivity is directly proportional to length . 2. area of cross section - if the area of the corresection of a wire is doubled by taking a thicker wire the resistance is half of the previous value . if radius is double the resistance will become one fourth . resistance of the conductor is inversely proportional to the area .
3. the resistance of the conductor depends on the nature of material of the conductor. 4. the resistance with increases with increase in its temperature
you are saying reverse

Featured snippet from the web
The resistivity of a material is the resistanceof a wire of that material of unit length and unit cross-sectional area. The unit for resistivity is the ohm-metre. Theresistivity of a materialdepends on its nature and the temperature of theconductor, but not on its shape and size.
