Question

Calculate the area of cross-section of a wire if it's length is 1.0m, it's resistance is 23ohm and the resistivity of the material of the wire is 1.84 × 10 ^-6ohm meter.

Answer 1

Explanation:

Calculate the area of cross section of a wire, if its length is 1.0m, its resistance is 23Ω and the resistivity of the material of the wire is 1.84 × 1O-6 Ωm. Therefore, the area of cross-section of the wire is 8 × 10-8 m2.
