Question

A wire of resistivity p is doubled on itself what will be its new resistivity​

Answer 1

Answer:

Resistivity is a property of the wire which does not depends upon the length or cross-sectional area of the wire.

Thus increasing the length will not effect the resistivity of the wire.

Hence the new resistivity of the wire will be p

Answer 2

Answer:

resistivily is property of the wire which does not depent upon lenght

thus the lenght of wire incresing does not effect the resistivily of wire
