Question

What is the electrical quantity that affects both resistance and resistivity of a substance? Explain why. ​

Answer 1

Answer:

Then the factors which affect the resistance (R) of a conductor in ohms can be listed as:

The resistivity (ρ) of the material from which the conductor is made.

The total length (L) of the conductor.

The cross-sectional area (A) of the conductor.

The temperature of the conductor.

Answer 2

Answer:

The resistivity represents the resistance of the material which has specific dimensions, i.e., the material has 1-meter length and 1 square meter area of cross section. The SI unit of resistivity is ohm meter. The resistivity is directly proportional to the temperature of the material.
