What does a Megawatt represent?

• A. 1,000,000 joules
• B. 1,000,000 watts
• C. 1,000,000 volt-amperes
• D. 1,000,000 ohms

Answer: (B)

A megawatt is a unit of power equal to one million watts. The prefix mega means 10^6, so it represents the rate at which energy is transferred or work is done, not the total amount of energy itself. One watt is one joule per second, so a megawatt is 1,000,000 joules per second. This is why the term describes power (the rate of energy flow) rather than just energy. It’s also distinct from volt-amperes (apparent power) and ohms (resistance). In practice, megawatts are used for large-scale electrical generation and distribution; aircraft systems, by contrast, are typically measured in kilowatts.
