Question

A wire of resistivity p is stretched to double its length.
What will be its new resistivity?
​

Answer 1

Answer:

okay

Answer the questions then you will get a points.

Answer 2

Answer:

R=p×(L÷A)

Step-by-step explanation:

where R p are resistance and resistivity respectively

and A ,L is area and length of conductor or wire

so if length increased double

so resistivity will be half

and resistance will be double
