Electric Power(P) is the rate of doing work or it is the ratio of work(W) divided by the time is taken (t). The units of power are Watt or Kilowatt or Joules/second.

Hence by the relation,

1 watt = 1 J/s and 1 watt is the power of appliance which consumes energy at the rate of 1 J/s or 1 watt is defined as when 1 Joule of work is done on a particle in 1 second.
