Answer:
ρ = 1.6*10⁻⁸ Ω/m.
Explanation:
- Applying Ohm's Law to the wire, assuming that it can be treated as a pure resistance, the resistance of the wire can be obtained as follows:
- At the same time, we know that there exists a relationship between the resistance, the resistivity ρ, the length L and the area A of the wire, that is given for the following expression:
- The area of the circular section of the wire, can be expressed as a function of the diameter d, as follows:
- Replacing the left side of (2) by (1), and (3) on the right side, we can solve for the resistivity ρ as follows:
- ρ = 1.6*10⁻⁸ Ω/m
