Question 2

Two aquarium pumps are tested separately. Pump A operates at a current of 0.30 A and a potential difference of 6.0 V for 80 s. Pump B operates at a current of 0.20 A and a potential difference of 9.0 V for 60 s. Which statement correctly compares the energy transferred during these tests?

[1]
A

Pump B transfers 36 J36\ \mathrm{J}36 J more energy than pump A.

B

Pump A transfers 36 J36\ \mathrm{J}36 J more energy than pump B.

C

The pumps transfer equal amounts of energy.

D

Pump A transfers 252 J252\ \mathrm{J}252 J more energy than pump B.
