What is power and its SI unit?

We can define power as the rate of doing work, it is the work done in unit time. The SI unit of power is Watt (W) which is joules per second (J/s). Sometimes the power of motor vehicles and other machines is given in terms of Horsepower (hp), which is approximately equal to 745.7 watts.

How do you calculate energy units?

For instance, If you switched ON a 1000 watt bulb for 1 hour, It means you have consumed 1000 watts for an hour i.e. (1000 watts for 1 hour = 1kWh = 1 unit of energy).
