Which term represents the rate of electrical power equal to 1,000 watts?

• A. Volt (V)
• B. Kilowatt (kw)
• C. Ampere (A)
• D. Polarity

Answer: (B)

Power in electricity is measured in watts, which expresses how fast energy is being used. When that rate is 1,000 watts, we call it a kilowatt. The prefix kilo- means thousand, so a kilowatt equals 1000 watts. Volt is the unit of electrical potential difference, and ampere is the unit of current. Polarity describes the direction of electrical charge, not a measure of power. Also, kilowatt-hour is a unit of energy (consumed over time), not the instantaneous power. So the term for 1,000 watts is kilowatt.
