On what factors, does the potential gradient of the potentimeter wire depend?

Explanation

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}
