A given wire is stretched to double its length. How will its resistance change ?

Explanation

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

### Step-by-Step Solution:

1. **Understand the Formula for Resistance**:
The resistance \( R \) of a wire is given by the formula:
\[
R = \frac{\rho L}{A}
