Answer:

Therefore, the electrical conductivity of the wire is approximately 5.0 * 10^3 S/m.

Step-by-step explanation:

To calculate the electrical conductivity of the wire, we can use the formula:

Electrical conductivity (σ) = (1 / Resistivity)

The resistivity (ρ) can be calculated using the formula:

Resistivity (ρ) = (Resistance x Cross-sectional Area) / Length

Given:

Length (L) = 200 cm

Cross-sectional Area (A) = 2.0 * 10^(-3) cm^2

Resistance (R) = 0.20

First, let's convert the length to meters:

L = 200 cm = 2 meters

Now, let's substitute the values into the resistivity formula:

ρ = (0.20 * 2.0 * 10^(-3)) / 2

ρ = 0.20 * 10^(-3) = 2.0 * 10^(-4)

Finally, we can calculate the electrical conductivity:

σ = 1 / ρ

σ = 1 / (2.0 * 10^(-4))

σ ≈ 5.0 * 10^3 S/m

Therefore, the electrical conductivity of the wire is approximately 5.0 * 10^3 S/m.
