A. Power
B. Electric Current
C. Energy
D. Time
E. None of these

Kilowatt hour is the unit of ENERGY.
Watt or Kilowatt is the unit of power.

Kilowatt-hour (KWh) is unit of Electrical Energy.
We know that, Power×time=Energy
⇒ Kilo-Watt×Hour=Energy
1KWh is electrical energy consumed when an electrical equipment of power 1 KiloWatt is operated for 1 Hour.
It is also used as commertial unit of energy in households/Buildings/Factories etc where 1 Unit of electricity is equivalent of 1KW-h of energy.

  1. Admin kindly confirm this answer because joule is the SI unit of energy and kilo watt per hour or watt per hour is the unit of power. So kindly check and confirm.

    1. Kilowatt hour is the unit of ENERGY.
      Watt or Kilowatt is the unit of power.
      So kindly correct the key .. Thanks

  2. power=Energy/ time or power=work-done/time
    Energy=Power*Time
    Hence, Kilowatt-Hour is unit of energy.

  3. Kilowatt-hour (kWh) is unit of energy, amount of energy used in one hour by any 1 kW appliance, Kindly confirm and make correction, correct answer should be Energy.

  4. One thousand Watts is one kilowatt, abbreviated kW. That’s a measure of power. If you use one kilowatt of power for an hour, you have used 1 kilowatt-hour, abbreviated kWh, of energy. One kilowatt-hour is equivalent to the energy of 1,000 joules used for 3,600 seconds or 3.6 million Joules. So, correct answer is Energy

  5. O bhai its the unit of energy, if it had watt or kilowatt then it would have be the unit of power… And the equation of enery is equal to power multiplied by time and kilowatt hour is therefore commercial unit of energy.

  6. O bhai its the unit of energy, if it had watt or kilowatt then it would have be the unit of power… And the equation of enery is equal to power multiplied by time and kilowatt hour is therefore commercial unit of energy.

  7. Kilowatt-hour has always been the unit of Electrical Energy. One kwh is equal to one unit of energy which is mentioned in bills too. Refer any book you want or even check the intermediate physics books, you will find your answer. Correct it, kwh is the unit of “ENERGY”.

  8. Kilowatt hour= Power x time
    But Power = Work/Time
    Kilowatt-hour becomes (Work/Time) x (Time)
    Time will be cancelled and remaining will be work aka energy.

  9. Kilowatt hour is the unit of energy not power.it is commercially used for electrical energy equal to 3.6 mega joule.
    Plz correct it

  10. admin kinly change it the correct answer is Energy only watt is unit of power
    kilo watt is unit of electrical energy

  11. “Kilo watt hour” is the unit of energy.
    “Watt” or “kilo watt” are the units of Power…

  12. It’s the unit of energy not power or hmary electricity k bills kilo watt hour jin ko hum units kehty hain ye wohi ek chez hain please correct this answer or ye fsc part 1 punjab text book me bi mention hai

  13. Energy is the right answer.
    Electric Energy in kJ= Power in kWatts multiply by time in hour

  14. Unit representations — The kilowatt-hour is a unit of energy equal to one kilowatt of power sustained for one hour or 3600 kilojoules (3.6 megajoules).
    SI units: 3.6 MJ

  15. Admin plz correct the answer kilo watt-hour is unit of energy whereas kilowatt is unit of power . Kindly check Wikipedia for clearing your confusions.

  16. kWh can also be expressed as the standard unit of energy in S.I. units. It is represented by using symbol ‘J
    ’. Relation between kWh
    and J
    is
    1kWh=1kW×1hour
    —(i)
    1hour=3600seconds

    Substituting this value in equation (i),
    1kWh=1000Watt×3600seconds

    1kWh=3.6×106J


    Kilo-watt hour is the unit of electric energy.

  17. Kilo-watt hour is the unit of electrical energy,100% confirm.Hence all the options are wrong.

  18. salam ! Dear Please Check from google because when i checked the answer is energy . energy is base and power is its component. please correct,. jin logon ny power jwab dia hai unko salam hai. or phly google sy confirm kr k update kia krein

  19. It is the unit of energy.
    Energy= power * time
    Kwh = watt* hour
    K mean 10 e3

  20. Kilowatt-hour is the unit of energy not power. The unit of power is watt, and when it is multiplied by time, we get energy. Kindly update it.
