A copper wire iis stretched to make it `0.1%` longer. What is the percentage change in its resistance?

Explanation

To solve the problem of finding the percentage change in resistance when a copper wire is stretched to make it 0.1% longer, we can follow these steps:

### Step 1: Understand the initial conditions
Let:
- Initial length of the wire = \( L \)
- Initial area of the wire = \( A \)
- Initial resistance of the wire = \( R \)
