Dear Suraj,

● Answer -
Power is a measure of *the rapidity with which work is done*.


● Power -
- Power is simply defined as rate of transfer of energy.
- It's calculated as work done per unit time -
P = W/t = ∆E/t
- Unit of power is Watt (W) which is same as J/s.
- 1 horsepower = 746 Watt



Hope this helped you. Thanks for asking dear.
