Question

What is a unit?

  1. Commercial unit of energy
  2. 1 kWh
  3. 3.6  × 106 J
  4. All of the above

hintHint:

A unit (as mentioned on the electricity bills) is represented in kWH or Kilowatt Hour.

The correct answer is: All of the above


    • A unit (as mentioned on the electricity bills) is represented in kWH or Kilowatt Hour. This is the actual electricity or energy used. If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWh) of electricity.
    • And 1kWh= 3.6 cross times 10 to the power of 6 J
