Four students are each given an identical resistor and asked to find its resistance. They each measure the potential difference across the resistor and the current in it.
One student makes a mistake.
Which row shows the results of the student that makes a mistake?
| Potential difference / V | Current / A | |
|---|---|---|
| A | 2.0 | 0.40 |
| B | 3.5 | 0.70 |
| C | 4.5 | 0.80 |
| D | 5.5 | 1.10 |
