Hope it helps :)

Answer 2

Definition of power -
Power is defined as the rate of transfer of energy .
Or
Power is defined as the rate of doing work
Power is given by :
P = W / t
where W = work
t = time.

The unit of power is Watt which is named in honor of James Watt.

Definition of 1 Watt :

1 Watt is the power of an agent , which does the work at the rate of 1 Joule per second.
OR
When the rates of consumption of energy is 1 J /sec , then we can say that the power is 1 W .

I Watt = 1 J / sec
