Question

5. Resistivity of a given copper wire of length 2m is 1.7 x 10 m. The wire is
stretched so that its length becomes 4m. Find new resistivity of the copper
copper wire

its urgent plz​

Answer 1

Answer:

The resistivity of a wire depends on its temperature and the material it is made up of .

Hence as the temperature and the material it is made up of remains the same the resistivity of the copper wire remains the same
