Question

Give SI unit and commercial unit of electrical energy.

Answer 1

• The standard international unit is Joules. It is obtained by multiplying the force with the distance covered.

• Commercial unit of energy is regarded as Kilowatt hour.

Here 1 KWH=1000*3600 seconds

• =3.6*106 Joules

• The units are different to calculate the energy bill on a prorate basis

Answer 2

Answer:

Commercial Unit Of Energy =kWh

Explanation:

Commercial Unit of Energy. The SI unit joule is too small to express very large quantities of energy. Hence we use a bigger unit called kilowatt hour (kWh) to express energy. 1kWh is the amount of energy consumed by an electrical gadget in one hour at the rate of 1000 J/s or 1kW.

Commercial Unit Of Energy =kWh

            SI Unit Of Energy = Joule (J)

1kWh=1kW×1h

=>1000W ×3600s

1 watt - second = 1 joule

1kWh=3600000J
