00:00hello everyone welcome to my youtube channel dear students and viewers today

00:14we will prove that 1 kilowatt hour is equal to 3.6 into 10 raised power 6 joule

00:24or 3.6 mega joule is 1 kilowatt hour is equal to as we know that the unit of

00:44power is watt so 1 kilowatt 1 kilowatt is equal to 10 raised power 3 watt means

00:591000 watt and 1 hour is equal to 3600 seconds or we can also write it as 3.6

01:13into 10 raised power 3 second so 1 kilowatt hours will be so we will place

01:2410 raised power 3 watts in place of 1 kilowatt into 1 hour which is equal to

01:353.6 into 10 raised power 3 second so 1 kilowatt hours will be equal to 3.6

01:49into is in multiplication when the bases are same then we will add the powers so

01:57it will be 10 raised power 3 plus 3 it will be 6 watts into second so 1 kilowatt

02:10hours will be equal to 3.6 into 10 raised power 6 is what is equal to joule upon second

02:21so into second second will be get cancelled with second so 1 kilowatt hours will be equal

02:31to 3.6 into 10 raised power 6 joule is kilowatt hours is the unit of energy so the unit of

02:42energy is joule as we know that 1 mega joule is equal to 10 raised power 6 joule so hours

02:57we can also write 1 kilowatt hours is 3.6 mega joule so this is our required condition

03:14I hope you have understood it in a very well mannered thank you
