A kilowatt is equivalent to which of the following?

A kilowatt is equivalent to which of the following?

• A. 0.67 amperes at voltage of 120
• B. 746 watts
• C. 1.34 horsepower
• D. 1000 megacycles

Answer: (C)

Understanding power units helps connect watts, kilowatts, and horsepower. A kilowatt equals 1000 watts, and one mechanical horsepower is defined as about 746 watts. So 1 kilowatt is 1000/746 ≈ 1.34 horsepower. That’s why the statement about 1.34 horsepower is the correct equivalence. The other options don’t fit: 0.67 amperes at 120 V would give about 80 W (P = VI), not 1000 W; 1000 megacycles is a frequency unit (MHz), not power; 746 watts is the amount of power in one horsepower, not in a kilowatt.
