Answer 2

Answer:

(A)Commercial Unit of Energy.

The SI unit joule is too small to express very large quantities of energy.

(B) Hence we use a bigger unit called kilowatt hour (kWh) to express energy.

1 kWh is the amount of energy consumed by an electrical gadget in one hour at the rate of 1000 J/s or 1kW.
