A wire of resistance 5`Omega` is bent in the form of a closed circle. Find the resistance across the diameter of the circle.

Explanation

To find the resistance across the diameter of a wire bent in the form of a closed circle, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Problem**:
- We have a wire with a total resistance of \( R = 5 \, \Omega \) that is bent into a circular shape. We need to find the resistance across the diameter of this circle.

2. **Dividing the Wire**:
