Question Discussion & Solution

• Power: The rate of work done by the electric energy is called power. It is denoted by P.
  • The SI unit of power is the watt (W).
  • Watt is a small unit that's why kilowatt-hour is used as the unit for electrical energy.
• 1 unit of electric energy: When one-kilowatt load works for 1 hour then the energy consumed is called 1 unit of electricity.

1 Unit of electricity = 1 kWh = 1000 Watt-hour = 3.6 × 106 J

1 Kilo-watt = 1000 Watt

• 1 Watt: The energy consumption rate of 1 joule per second is called 1 watt.

EXPLANATION:

Since 1 hr = 3600 sec

1 kWh = 1000 W-hr = 1000 × 3600 watt sec = 3.6 × 10⁶ J 

​So option 1 is correct.

The correct answer is constitutional authority.
