Answer
The SI unit of power is the watt (W), named after Scottish engineer James Watt. One watt equals one joule of energy per second, or in electrical terms, one volt-ampere (1W = 1V × 1A). Common multiples include kilowatts (1000W) for household appliances and megawatts (1,000,000W) for large-scale power systems.
