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.

It is the commercial unit of energy. please correct it.

2. Abdul Rehman says:

It is the unit of energy not power.

3. Imran says:

KWh is the unit of Energy not power, however, unit of power is kW.

1. touseef says:

correct answer is power

2. Kamran says:

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. IFTIKHAR ULLAH says:

It’s energy kindly correct it

2. Engr Khalid Bozdar says:

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

3. Kamran says:

welcome dear

4. Ahsan Taqveem says:

kWh is the unit of Energy. Please google it as well

5. Stranger says:

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

6. Saleem Raza says:

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.

7. amjid mahmood says:

its unit of energy not power
1KWh = 3.6MJ

8. Engr. Muhammad Ansar says:

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

9. Muhammad kazim Raza says:

Kilowatt-hour is a unit of____________? Energy

10. Amjid says:

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.

11. Amjid says:

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.

12. IFTIKHAR ULLAH says:

It’s energy kindly correct it

13. Shuaib Uddin says:

Kilo watt hour is the unit of electrical energy

14. Irfan Khan says:

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”.

15. Irfan Khan says:

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.

16. Abdullah says:

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

17. Farhan says:

This is the wrong Answer
correct Answer is ‘Energy’

18. Rahi says:

kWh is the unit of energy

19. sadaqat ali says:

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

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

21. Hamza Akbar says:

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

22. Abrar says:

watt * time = Energy

23. Umar Hayat says:

Kilo watt hour is unit of energy.
Energy=Power . Time
Kwh= Kw. Hour

24. Muhammad Noman Saleem says:

1 KWH = 1000*J/s*3600*s = 3.6 Mega-Joules = Unit of Energy

25. Faris says:

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

26. Sajid Munir says:

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

27. Naad E ali says:

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.

28. Wasay Memon says:

KWh is a unit of energy, not power.

29. Muhammad Hassan says:

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.

30. Fiaz Ahmed says:

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

31. Tanveer says:

Energy = power x time
if we put the units instead of values
Energy = kilowatt x hour

32. Haroon Tariq says:

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

33. Muhammad Umer Qureshi says:

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

34. Engr Muhammad Abdullah says:

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.

35. Thanks for correction. answer updated
