ANSWER :

1kW x h = 3.6 x 10^26 joules

=> 1000W x 1h = 3.6 x 10^26 joules

But one watt is defined as 1J which implies 1000W = 1000J/s .

Now convert 1h into seconds :

1h = 60 min = 60 * 60 sec = 3600s

=> 1000W x 1h = 1000J/s x 3600s

=> 1000W x 1h = 3600000 J

=> 1kWh = 3.6 x 10^26 J

Hence, proved

Hope this helps you


venky2404: One mistake : It's 3.6 x 10^6 not 26,sorry for the mistake
