Question

How is the SI unit of electric energy related to its commercial unit?​

Answer 1

Answer:

The commercial unit of energy is 1 kWh. One kilowatt-hour is defined as the amount of energy that is consumed by a device in one working hour at a constant rate of one kilowatt.

The SI unit of energy is Joule.

Therefore, the relationship between commercial and SI unit of energy is:

1 kWh = 1kW x 1h = 1000W x 1h = 1000(J/s) x 3600 s = 3.6 x106 J

Hope this helps you stay safe

Answer 2

Answer:

1kWh = 1000 × 60 × 60

1kWh = 3.6 × 10⁶ J

The commercial unit of electrical energy is a kilowatt-hour (kWh).
