why resistivity depends only on nature and temperature not on length and cross section area ?
plz give correct explanation...

Answer:
It is the longitudinal electrical resistance of a uniform rod of unit length and unit cross-sectional area. The reciprocal of conductivity is resistivity. The resistivity of a material depends on its nature and the temperature of the conductor, but not on its shape and size.

Answer:
it depends on the material resistance of wire of that material of unit length and unit cross sectional area material depends on its natural and temperature of the conductor but not on its shape and size.
- length of conductor
- temperature
- natural
Hope it's help
