The resistivity of the material of a wire is 1. 76 × 10-8 ωm. if the diameter of the wire is 2 × 10-3 m and its length is 2 m, what is its resistance?

The resistivity of the material of a wire is 1. 76 × 10-8 ωm. if the diameter of the wire is 2 × 10-3 m and its length is 2 m, then its resistance is  0.0112Ω

The resistance of a wire is solely determined by its length, cross-section area, and resistivity. So we calculate the resistance of a wire by knowing its diameter, length, and resistivity (which varies depending on the material). The resistance provided by a unit length of conductor with a unit area of cross-section is defined as resistivity. Its SI unit is the ohm-meter.

It does not alter as the wire length increases, but resistance increases fourfold when the wire is stretched to double its original length. Resistivity is defined as the electrical resistance per unit length and cross-sectional area of a conductor.
