The Kilowatt Hour - A Level Physics

This video introduces and explains the kilowatt hour (kilowatt-hour) for A Level Physics. The kilowatt hour (kWh) is the unit of energy that we use in our homes. Because we use so much energy, measuring our energy consumption in joules is impractical. So instead, we use the kilowatt hour. 1 kilowatt hour is equal to 1kW x 1hour = 1 000 x 60 x 60 = 3 600 000 J.
