What does one kilowatt (kW) equal?

• A. 1,000 volts
• B. 1,000 watts
• C. 1,000 amperes
• D. 1,000 joules

Answer: (B)

One kilowatt (kW) is a unit of power that is defined as equal to 1,000 watts. Power is a measure of the rate at which energy is used or generated, and the watt is the standard unit for this measurement in the electrical system. To understand this concept further, consider that one watt is equivalent to one joule per second (1 W = 1 J/s), which means that a kilowatt, being 1,000 watts, represents a rate of energy transfer of 1,000 joules per second. This concept is essential in various fields, including utility marketing, as it allows representatives to quantify and communicate energy usage effectively. In practical applications, when discussing electrical devices, their power consumption is often measured in kilowatts, making it crucial for understanding energy efficiency and cost calculations for both consumers and providers.
