An engineer is testing four different miniature water pumps, $P_1$ , $P_2$ , $P_3$ , and $P_4$ , for use in a hydroponic irrigation system. The operating current and potential difference for each pump are recorded in the table below.

Pump	Current (A)	Potential difference (V)
$P_1$	1.4	15
$P_2$	2.6	12
$P_3$	3.6	9
$P_4$	1.8	16

Determine which pump has the highest power consumption.

Use the equation: $difference×current\text{power} = \text{potential difference} \times \text{current}$
