Question

The S.I unit of resistivity is?

• A. ohm m
• B. ohm
• C. ohm/m
• D. mho

Answer 1

Answer:

A. ohm m

• The SI unit of resistivity is the ohm-meter (Ω⋅m).

• It's a unit that measures how strongly a material resists the flow of electric current.

• Resistivity is an intrinsic property of a material that quantifies how strongly it opposes the flow of electric current.

• A higher resistivity value indicates that the material is a poorer conductor of electricity
