Electrical resistivity (also known as resistivity, specific electrical resistance, or volumeresistivity) is an intrinsic property that quantifies how strongly a given material opposes the flow of electric current.
Ω⋅m is its si unit use I = neAVd tp find its resistance
Ω⋅m is its si unit use I = neAVd tp find its resistance
