Question

a wire of resistivity is streched three times its original length .what will be its new resistivity

Answer 1

Resistivity is property of conductor. It depends only on temperature and nature of material.

So no matter how you change the shape of wire it's resistivity will remain constant.


Resistivity will remain constant but resistance will change. Don't get messed up with resistance and resistivity. Both are different.
