State whether the resistivity of a wire changes with the change in the thickness of the wire.

Explanation

To determine whether the resistivity of a wire changes with the change in thickness of the wire, we can analyze the relationship between resistivity, resistance, area, and length.

### Step-by-Step Solution:

1. **Understanding Resistivity**:
- Resistivity (ρ) is a material property that indicates how strongly a material opposes the flow of electric current. It is defined as:
\[
\rho = R \cdot \frac{A}{L}
