![**Example Problem on Electrical Resistance Calculation**
**Problem Statement:**
A coil is formed by winding 330 turns of insulated 16 gauge copper wire (diameter = 1.0 mm) in a single layer on a cylindrical form of radius 17 cm. What is the resistance of the coil? Neglect the thickness of the insulation. (Take the resistivity of copper to be 1.69 × 10^-8 ohm-m.)
**Solution Input:**
- Number: 6.0
- Units: Ohm (Ω)
**Explanation:**
To calculate the resistance of the coil, you need to use the following steps:
1. **Determine the Length of the Wire:**
The circumference of the cylinder, which the wire is wound around, is given by the formula:
\[
\text{Circumference} = 2 \pi \times \text{radius}
\]
Substituting the given radius (17 cm = 0.17 m):
\[
\text{Circumference} = 2 \pi \times 0.17 \approx 1.07 \text{ meters}
\]
Since the wire is wound 330 times around the cylinder:
\[
\text{Total length of wire} = 330 \times 1.07 \approx 353.1 \text{ meters}
\]
2. **Resistivity Formula:**
The resistance \(R\) of a wire is calculated using the resistivity formula:
\[
R = \rho \frac{L}{A}
\]
where:
- \(\rho\) is the resistivity of the material (copper), which is \(1.69 \times 10^{-8} \text{ ohm-m} \),
- \(L\) is the length of the wire (353.1 meters),
- \(A\) is the cross-sectional area of the wire.
3. **Determine the Cross-Sectional Area:**
The diameter of the wire is given as 1.0 mm, thus the radius is:
\[
\text{Radius} = \frac{1.0 \text{ mm}}{2} = 0.5 \text{ mm} = 0.0005 \text{ meters}
\]
