what is the difference between resistance and resistivity

Answers

Answered by lahore896

resistance is actually opposition offered to the flow of current and it is inversly propotional to capacitance

R = 1\C

and resistivity is specific resistance that is resistance of a conductor having unit length and unit cross sectional area

R = (row) L\A

lahore896: Yes i won . sorry mr munam abdullah but ab tum mry kise kaam ke nahe hoo me tum sy payar nahe kartee. Jo me chahti the wo me ne kar dia me zainab ko harana chahti the or aaj mein ny wo kar diaa .Pta ha keun jis larky sy me payar kartee thi wo zainab se payar karta tha ,haan zainab ny usy kabhi lift nahi karwaee but me zainab ko b wahi dard dena chahti thee jo mein ne bardasht kia ... aur dekho aj wo har gae aur mein jeet gae ... i am very happy today and i don't beed you now so don't message me

Answer:

Explanation:

Resistance is the obstruction offered to the flow of current by a conductor.

Resistivity is the obstruction offered to the flow of current by UNIT AREA OF the conductor.

So basically, resistance is the property of the object (say a copper wire), whereas resistivity is the property of the substance (copper).

And so resistance depends upon the properties of the object.

Whereas resistivity depends upon the properties of the metal.

So for example take two objects A and B made of aluminium. Both are of a different size.

The resistance of A & B will be different.

But the resistivity will be the same
