AI Generated Solution
To determine the factors on which the potential gradient of a potentiometer wire depends, we can follow these steps:
### Step-by-Step Solution:
1. **Understanding Potential Gradient**:
The potential gradient (K) of a potentiometer wire is defined as the potential difference (V) across the wire divided by its length (L). Mathematically, it is expressed as:
\[
K = \frac{V}{L}
