What is the SI unit of resistivity, and what is its submultiple unit often used?

Options

  1. ASI Unit: ohm (Ω), Submultiple: watt (W)
  2. BSI Unit: ampere ( A), Submultiple: ohm centimeter (Ω cm)
  3. CSI Unit: ohm meter (Ω m), Submultiple: ohm centimeter (Ω cm)
  4. DSI Unit: volt (V), Submultiple: watt meter (W m)

Correct answer

C. SI Unit: ohm meter (Ω m), Submultiple: ohm centimeter (Ω cm)

Step-by-step solution

The SI unit of resistivity is ohm meter (Ω m), and its submultiple is ohm centimeter (Ω cm).
