Question

Q3. Write two differences between resistance and resistivity.​

Answer 1

Answer:

Resistivity is the physical property of a particular substance which is having particular dimensions. Resistance is directly proportional to the length and temperature while it is inversely proportional to the cross-sectional area of the material. ... The SI unit of resistivity is Ohms-meter.

Answer 2

Answer:

Resistance is the property of a conductor to resist the flow of charges through it.

Resistance is the obstruction offered to the flow of current by a conductor.resistance depends upon the properties of the object.

Resistivity is the electrical resistance per unit length and per unit of cross-sectional area.

resistivity depends upon the properties of the metal.
