What is the unit of power?

Explanation:
Power is the rate at which energy is transferred, so its unit in the SI system is the watt. One watt equals one joule per second, meaning it measures how quickly energy is used or produced. Kilowatt is simply a larger unit of power (1 kilowatt = 1000 watts) often used for bigger devices. The other units reflect different electrical properties—ohm is resistance and volt is electric potential difference—so they don’t measure power. Therefore, the watt is the unit that directly represents power.
