Name the commercial unit of electrical energy. Convert it into joule. What is the other name of the commercial unit ?
The commercial unit of electrical energy is kilowatt-hour $(kW h).$
$1 kW \cdot h =1 kW \times 1$ hour
$=1000 W \times 3600 s$
$=1000 J s ^{-1} \times 3600 s$
$1 kWh =3.6 \times 10^{6} J$
It is also called Board Of Trade Unit $( BOTU).$
