Question

What is meant by one kilowatt hour ? Express 10 kWh into joule​

Answer 1

Answer:

One kilowatt-hour is equal to 3600000 joules: 1kWh = 3600000J = 3.6⋅106J = 3.6MJ. So the energy in joules E(J) is equal to 3600000 times the energy in kilowatt-hour E(kWh): E(J) = 3600000 ⋅ E(kWh)

Answer 2

Answer:

1kWh=1kW×1h

=1000W×3600s

=3600000J

=3.6×10
