Power 

    Power can be defined as the rate of work done. In other words - Power can be defined as the transfer or conversation of energy per unit time.

Formula

     Power = Work Done / Time

              P  = W/t

              P  = E/t

Where 

        P = power 

       W = Work Done (in joule) 

       t  = Time (in second) 

       E = Energy (in joule) 

SI unit of power is Watt. 

                     

 ∵  P = E/t

          = unit of energy / unit of time

          = joule / second

          = j/s

          = Watt

 ∵  1 j/s = 1 watt
