Length of the wire, l =15 m

Area of cross-section of the wire, a = 6.0 × 10 - 7 m2

Resistance of the material of the wire, R = 5.0 Ω

Resistivity of the material of the wire = ÃÂ

Resistance is related with the resistivity as

Resistivity of the material of the wire = ÃÂ

Resistance is related with the resistivity as

Therefore, the resistivity of the material is 2 × 10 - 7 Ω

Therefore, the resistivity of the material is 2 × 10 - 7 Ω
