Which statements are true for the resistivity of a metalconductor?
(1) It depends on the temperature of the material.
(2) It is positive for copper but negative for carbon.
(3) It is an intrinsic property of the conductor and is independentof the voltage applied to it.
(4) It has units of ohms/meter.
(5) It depends on the electronic structure of the material.
(6) It becomes smaller as the cross-sectional area of the materialbecomes smaller.
