Question

what is resistance and resistivity

Answer 1

The resistance of an object (i.e., a resistor ) depends on its shape and the material of which it is composed.Resistivity ρ is an intrinsic property of a material and directly proportional to the total resistance R, an extrinsic quantity that depends on the length and cross-sectional area of a resistor.

Answer 2

Hey mate!!!

➡️ Resistance :-
V =IR

where, R is called resistance and directly proportional to V

➡️ Resistivity :-
It can be defined as ratio of electric field applied to current density.

Resistivity = E/J
