Question

what is the difference between RESISTANCE AND RESISTIVITY?
Please explain​

Answer 1

Answer:

1) resistance is the opposition offered to flow of current by the conductor, whereas resistivity is the resistance of the conductor when current flows through a unit cross section conductor of unit length

2) resistance is dependent on dimension of conductor whereas resistivity is independent

3) S.I. unit of resistance is ohm whereas S.I unit of resistivity I'd ohm m

Answer 2

Answer:

Resistance:-

1. The property of the conductor due to which is opposes a flow of current through it is called resistance.
2. The SI unit of resistance is Ohm O.
3. The resistance of a conductor depends on its length and area of cross section.

Resistivity:-

1. The resistivity of a conductor is resistance of a conductor of unit length and area of cross section.
2. The SI unit of resistivity is Ohm- metre (m).
3. The resistivity of a conductor does not depend on its length and area of cross section.
