Question

If you have a device that draws 2 kilowatts of power, how much total energy in kilowatt-hours will it use if it runs for exactly 5 hours?

Accepted Answer

To find out how much energy a device uses, you just multiply its power by the amount of time it runs. Power is how fast a device uses electricity, and here your device uses 2 kilowatts. A kilowatt is just a way to measure a thousand watts of power at once. Since the device runs for 5 hours, you multiply the 2 kilowatts by 5 hours. This gives you 10 kilowatt-hours. A kilowatt-hour is simply the standard unit for the total amount of energy used over time. Think of it like a car speedometer: if you drive at a steady speed of 2 miles per hour for 5 hours, you have traveled a total distance of 10 miles. In the same way, your device used a total of 10 kilowatt-hours of energy.
