Yes, but the resistivity comes out to be 3.978×10-6 ohm-meter. You might not get full credit if you round that off to 4.Fatima Hasan said:
Resistivity is a measure of how strongly a material opposes the flow of electric current. It is represented by the Greek letter rho (ρ) and is measured in ohm-meters (Ω∙m).
Resistance is a measure of the difficulty for current to flow through a material, while resistivity is a property of the material itself. Resistivity takes into account the dimensions and composition of the material, while resistance does not.
Resistivity can be calculated by dividing the resistance of a material by its cross-sectional area and then multiplying by its length. The formula is ρ = RA/l, where ρ is resistivity, R is resistance, A is cross-sectional area, and l is length.
The resistivity of a material is affected by its composition, temperature, and impurities. Generally, materials with higher resistivity are poor conductors, while materials with lower resistivity are good conductors.
The resistivity of a resistive wire can be measured using a multimeter. First, measure the resistance of the wire using the multimeter. Then, measure the length and cross-sectional area of the wire. Finally, use the resistivity formula (ρ = RA/l) to calculate the resistivity of the wire.
