Question

what is the difference between resistance and resistivity​

Answer 1

Answer:

Resistance is the physical property of a substance because of which it opposes the flow of current i.e. electrons. Resistivity is the physical property of a particular substance which is having particular dimensions. ... Resistivity is only proportional to the nature and temperature of the particular material.

Answer 2

• Resistivity is also known as electrical resistivity.

• Its a property that quantities how strongly a material opposes the flow of electric current.

• A low resistivity indicates a material that allows the flow of electric current.

• Its SI unit is ohm (symbol - Ω).

• It's named after German physicist Georg Simon Ohm.

• Resistivity of a conductor is a property of the material of the conductor.  Unit of resistivity is Ohm meter, Ω m.

• Resistivity of the material of the conductor changes with temperature.

• Resistivity of copper is 1.7 × 10 -8 Ω m at room temperature.
