How can a given 4 wires potentiometer be made more sensitive ?

Explanation

To make a given 4-wire potentiometer more sensitive, we can follow these steps:

### Step 1: Increase the Length of the Wire
- **Solution**: The sensitivity of a potentiometer is directly proportional to the length of the wire used. By increasing the length of the potentiometer wire, we can achieve a greater potential difference for a given current, which enhances its sensitivity.

### Step 2: Use a Wire with Higher Resistivity
- **Solution**: Choosing a wire material with higher resistivity will also increase the sensitivity. A higher resistivity wire will produce a larger voltage drop across the length of the wire for the same current, thus improving the measurement accuracy.
