Question

show that 1kWh = 3.6 multiplied by 10 to the power 6 Joule.

Answer 1

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
