Difference between resistance and resistivity?
Answers
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:
⭕️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.
