Answer 1

1 watt (W) is 1 joule/second. k is kilo and means 1000, so 200kW is 200,000 joule/second.

Just multiply it with the time in seconds to get the total amount of energy.

kWh (kilowatt hours) are commonly used energy units for electricity. An hour is 3600 seconds so 1kWh = 1000joule/second * 3600 seconds =3,600,000 joule. Because the time electricity is used is often closer to hours not second it is a more convenient unit. It is important to remember that kWh is not a power or time unit it is an energy unit

This means if you change for 1 hour the energy is 200kWh, if you do that for 2 hours 400kWh.

Per minute it is 200/60 =3.3333… kWh so if you change for 5 minutes the energy is 16.7 kWh
