Question
What is a unit?
- Commercial unit of energy
- 1 kWh
- 3.6 × 106 J
- All of the above
Hint:
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=
J
