The commercial unit of electrical energy is the kilowatt-hour (kWh) which is also knwon as the Board of trade unit (B.O.T). 1 kwh = 1000 × 60 × 60 watt – second 1 kwh = 36 × 10 5 Ws or Joules Generally, one kwh is called one unit.

Power can be expressed in many different units, all of which can be expressed as a unit of energy divided by a unit of time. The most common unit is the watt (W), defined as 1 joule (J) of energy per second. A 40 W light bulb, then, uses 40 J of electrical energy every second to stay lit.

The SI unit of power is the watt, one joule per second. Electric power is usually produced by electric generators, but can also be supplied by sources such as electric batteries. It is usually supplied to businesses and homes (as domestic mains electricity) by the electric power industry through an electric power grid.

The rate at which the heat is dissipated is called power, and is measured in units of watts ( W ). To find the power (P) using V and I, we use P = V I. Here, the unit of Voltage (V) is volt and Current (I) is ampere. Hence, the unit of electric power can also be expressed as volt ampere.
