Explanation:

Commercial Unit of Electric Energy:

The unit ‘watt’ is very small. So, practically a much larger unit called ‘kilowatt’ is used. It is equal to 1000 watts. Since electrical energy is the product of power and time, the unit of electric energy is, therefore, watt hour (Wh).

One watt hour is the energy consumed when 1 watt of power is used for 1 hour.

The commercial unit of electric energy is kilowatt hour (kWh), commonly known as ‘unit’. One kilowatt hour is the energy consumed when 1000 watt of power is used for 1 hour.

1 kW h = 1000 watt × 3600 second

= 3.6 × 106 watt second

= 3.6 × 106 joule (J) (where joule ‘J’ is the S.I unit of energy.)
