Answer 2

Explanation:

Power spent by a source depends on two factors:

(i) The amount of work done by the source, and

(ii) The time taken by the source to do the said work.

Example: If a coolie A takes 1 minute to lift a load to the roof of a bus, while another coolie B takes 2 minutes to lilt the same load to the roof of the seine bus, the work done by both the coolies is the same, but the power spent by the cootie A is twice the power spent by the coolie B because the coolie A does work at a faster rate.
