hello!
What is the difference between resistor, resistance and resistivity?

Answer 1

Answer:

Resistor and resistance are same . It is name of object .

And resistivity is const which is different for different materials of resistance

Resistivity =resistance ×length/area of cross section unit of resistance =ohm

Resistivity =ohm /meter

Explanation:

Answer 2

Explanation:

The resistance is the ratio of the length and cross-section area of the conductor, whereas the resistivity of the material is the ratio of the product of the resistance and area to the length of the conductor. The resistance is represented by the symbol R whereas the resistivity is represented by the symbol ρ.
