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
