Question

Resistivity is independent of

• A. length of the material
• B. Cross section area of the material
• C. Nature of the material
• D. both (a) and (b)

Answer 1

The correct option is D both (a) and (b)

Electrical resistivity (also known as resistivity, specific electrical resistance) is an intrinsic property that quantifies how strongly a given material opposes the flow of electric current.
As it is intrinsic property it only depends on the material but not the other factors like length and cross sectional area.
