Answer 1

HEY DEAR YOUR ANSWER IS HERE

The watt-hour (symbolized Wh) is a unit of energy equivalent to one watt(1 W) of power expended for one hour(1 h) of time. The watt-hour is not a standard unit in any formal system, but it is commonly used in electrical applications. An energy expenditure of1 Wh represents 3600 joules (3.600 x 103 J).

Answer 2

in 1 hour there are 3600 sec.
1watt =1 joule
