The table shows the current and potential difference for four different electrical appliances.
| Appliance | Current (A) | Potential difference (V) |
|---|---|---|
| W | 1.5 | 12 |
| X | 3.0 | 9 |
| Y | 4.0 | 6 |
| Z | 2.5 | 10 |
Which appliance has the highest power?
Use the equation: power=potential difference×current\text{power} = \text{potential difference} \times \text{current}power=potential difference×current
