Answer
The two factors on which the power spent by a source depends are :
- The amount of work done by the source
- The time taken by the source to do the said work.
For example:
Let us suppose a man X takes 5 minute to lift a load to the roof of a house and a man Y takes 10 minutes to lift the same load to the roof of the same house.
The work done by both the persons remain the same, but the power spent by the man X is twice the power spent by the man Y because man X does the work faster than man Y.
