Question

Power ________ is of doing work.

Answer 1

1. Power(P) is defined as the rate at which work(W) is done, i.e. power (P) is the measure of how fast work (W) is done.
2. $Power\left(P\right)=\frac{Workdone\left(W\right)}{Time\left(T\right)}$
3. The unit of power is joule per second.
4. It is also called Watt (W).
5. If the work done by a machine is 1 joule in a time of 1 second, then the power of the machine is 1 watt.

Hence, the power of the machine is the watt.
