A metallic wire having a resistance of `20Omega` is bent in order to form a complete circle. Calculate the resistance between any two diametrically opposite points on the circle.

Explanation

To solve the problem of finding the resistance between two diametrically opposite points on a circular wire with a total resistance of 20 ohms, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Configuration**:
- We have a metallic wire with a total resistance of 20 ohms that is bent into the shape of a circle.
- We need to find the resistance between two points (A and B) that are diametrically opposite to each other on the circle.
