Distinguish between resistance and resistivity of a conductor by listing two features of each.
Answers
Explanation:
For a conductor, the resistance is directly proportional to the length of the conductor and inversely proportional to the area of cross-section. ... Resistivity is defined as the resistance offered by the material per unit length for unit cross-section.
Answer:
resistance= it is the physical property of substance because of which it opposes the flow of current i.e.electrons.
1) it is the of a conductor to resist the flow of charges through it.
2) it's unit is OHM
3)resistance depend on length,cross sectional area of the wire, and material medium that depends on its temperature .
resistivity = it is the physical property of particular substance which is having particular dimensions.
1) it is the resistance per unit of a unit cross section of a material.
2) it's unit is OHM meter
3)resistivity is a constant value for the conductor only at a given temperature. it varies with temperature P. T resistivity
