Answer:
The resistivity of the two parts will be same. If we cut the wire into two equal parts then the length will be change of the wire but will not change the resistivity of the wire.

Answer:
What happens to the resistivity of a wire when it is double folded?
There are no change in Resistivity of wire when it is double folded. because it is independent of conductor size or shape. it is same for specific material like resistivity of copper is 1.68 × 10⁻⁸ Ωm.
