Question

What do you mean by resistivity of conductor factors on which resistance of a conductor depends?

Answer 1

resistance depends on 
1 length of conductor
2 area
3 temperature 
4 nature of conductor 

resistivity is the sign of proportanility which is used to show the relation of resistance to length and area of conductor.

Answer 2

$\huge \mathcal \green{ANSWER - }$

Resistance of a conductor depends on:

(a) Length of a conductor. Resistance of a conductor is directly proportional to the length of a conductor. If length increases resistance will also increase.

(b) Area of cross section of a conductor. The resistance of a conductor is inversely proportional to the area of the cross section of a conductor.

(c) Effect of material of a conductor. The resistance of a conductor also depends on the material of a conductor.

E.g. The resistance of nichrome wire is 60 times more than that of copper wire as nichrome has high electrical resistance.

(d) Effect of temperature. The resistance of all pure metals increases on increasing the temperature and decreases on decreasing the temperature.
