Question
Distinguish between resistance and resistivity.
✓

Answer

  1. Resistance is the property of the conductor, while resistivity is the property of the material of the conductor.
  2. Resistance of a conductor is the opposition to the flow of electric current through it. resistivity of a substance is the opposition to the flow of electric current by a rod of that substance which is 1m long and 1m2 in cross section.
  3. Resistivity of a substances depends on the nature of the substance and temperature.
  4. Resistivity of a substance on the nature of the substance and its temper. it does not depend the length or thickness of the conductor.
