Question

What is the necessity of using term ‘Average Power’ instead of power?

Answer 1

Average Power:

1. The ratio of total work done by the total time taken is called average power.
2. Machines may perform work at different intervals of time at different rates. In this situation, it is difficult to calculate power so we use average power instead of power by dividing the total energy consumed by the total time taken.
3. $Averagepower=\frac{Totalenergyconsumed}{Totaltimetaken}$
