Question

change in resistance to a considerable range of
temperature,
1 point
0.1.1 What happens to the
resistivity of a wire if it is
stretched to double its initial
length?"
(a) It will increase and becomes
double
O (b) It will decrease and become half
() First increases then decreases
(d) Remains the same​

Answer 1

The Resistivity of the wire will not change with the change in length. Resistivity is a property of the wire, it doesn't depend upon it's length or cross-sectional area.
