Which of the following is correctly matched?
Electric energy - Kilowatt hour
The correct answer is Electric energy - Kilowatt hour.
The kilowatt-hour is particularly important in electrical billing as it represents the energy consumed by using 1 kilowatt of power for 1 hour. 1 Joule = 1 Watt ⋅ second 1 Kilowatt-hour = 1000 Watt ⋅ 3600 seconds = 3,600,000 Joules Kilowatt minute and kilowatt second, while not as commonly used as kWh for billing, are also valid units of energy derived from Power × Time.
