Question

The electrical
resistivity of a conductor depend upon

Answer 1

Answer:

The unit for resistivity is the ohm-metre. The resistivity of a material depends on its nature and the temperature of the conductor, but not on its shape and size. ... Conductivity is the reciprocal of resistivity, and determines the ability of a material to conduct electric current.

Answer 2

Electrical resistivity depends upon temperature. If conductor is a metal then when we increase temperature the resistance will increase while in alloys it doesn’t necessarily to happen.
It also depends upon material of the conductor. Example- Rubber will have more resistivity than copper
