Question

A copper wire of resistivity is strecthed double its lenght. what is the new resistivity

Answer 1

The factors on which the resistivity depends are --

1) Nature of the conductor
2) Temperature supplied.

The resistivity doesn't depend on shape or size of the conductor.

So in this case, the resistivity will remain the same.

Hope This Helps You!

Answer 2

Hello friends...

We know that the specific resistance i.e .the resistivity depends on two factors

(1.) On Temperature
(2.) On meterial of the conductor

Here
The resistivity of conductor not depends on length of the conductor

Hence
When we stracthed the conductor to double the length
Resistivity doesn't change..
Remains the same
