Kilowatt is a unit of power equal to 1000 of which unit?

• A. Watt
• B. Ohm
• C. Ampere
• D. Volt

Answer: (A)

Power is the rate at which energy is transferred or work is done. In the SI system, power is measured in watts. A kilowatt equals 1000 watts, and a watt is defined as one joule per second. That’s why household and appliance ratings use watts or kilowatts. For context, a kilowatt is a common size for larger electrical devices, while a watt is typical for smaller ones. The other units listed—ohm, ampere, and volt—measure different properties (resistance, current, and voltage, respectively). Power can be found from voltage times current (P = V × I), which ties these quantities together when assessing energy transfer.
