define power. Give the SI unit of power
The rate of doing work is power.its SI unit is watts
Power is defined as the rate of work done.
Power (P) is given by the ratio of work done (W) and time taken (t) to do that work i.e.
Whenever work is done, an equal amount of energy is consumed. Hence, we define power as
The SI unit of power is watt (W) in honour of physicist James Watt.
