A given wire of resistance 1 `Omega ` is stretched to double its length. What will be its new resistance ?

Explanation

To find the new resistance of a wire when it is stretched to double its length, we can follow these steps:

### Step 1: Understand the relationship between resistance, length, and cross-sectional area
The resistance \( R \) of a wire is given by the formula:
\[ R = \frac{\rho L}{A} \]
where:
