Fractured Physics. People often call their electric bill a power bill, yet the quantity on which the bill is based is expressed in kilowatt-hours. What are people really being billed for?

Solution 9DQ In the unit kilowatt-hour, the kilowatt represents the power and the horu represents the time. Hence the unit is the multiplication of power with time. We know that power multiplied by times gives us energy. Hence the kilowatt-hour represents unit of time. So people are billed for energy.
