What is resistivity?

  1. Resistivity is a measure of the material's ability to dispose electric current.

  2. Resistivity is a measure of the material's ability to increase electric current flow through it.

  3. Resistivity is a measure of the material's ability to decrease electric current flow through it.

  4. Resistivity is a measure of the material's ability to oppose electric current.

D Correct answer
Explanation

Resistivity is an intrinsic property of a material that measures its ability to oppose electric current flow. It is independent of the material's dimensions and depends only on the material's composition and temperature. The correct definition states that resistivity measures the opposition to current, not the disposal or increase of current. Options A, B, and C incorrectly describe resistivity as facilitating current rather than opposing it.
