What is the unit of measurement for power?

Power is measured in Watts, which is the correct answer. The Watt is defined as one joule per second and represents the rate at which energy is used or generated. In electrical systems, power can be calculated by multiplying voltage (in Volts) by current (in Amperes). Hence, when discussing electrical power, Watts serve as the standard unit of measurement to describe energy consumption or production over time.

For context, the other choices represent different electrical parameters: Volts measure voltage, which is the electric potential difference allowing current to flow, Amperes measure the flow of electric current, and Ohms measure electrical resistance. Each of these units plays a critical role in understanding electrical circuits, but they do not quantify power directly. Only Watts provide the necessary context of how quickly energy is being converted or consumed in an electrical system.
