If the length of a copper wire is increased by twice, then its resistivity will be

Options

  1. ADoubled
  2. BHalved
  3. CSame
  4. DOne-fourth

Correct answer

C. Same

Step-by-step solution

Resistivity is an intrinsic property of a material. It depends only on the nature of the material and its temperature. It is independent of the physical dimensions such as length and area of cross-section of the wire. Therefore, when the length of the copper wire is increased, its resistivity remains the same. Answer: Same
