What does the term "watt" measure?

The term "watt" measures the rate of electrical power consumed. This unit quantifies how much energy is used or produced per unit of time in an electrical system. Specifically, one watt is equivalent to one joule per second, indicating the efficiency and capacity of electrical devices. Understanding watts is crucial for evaluating the power requirements of appliances and electrical systems, allowing for effective energy management and consumption decisions. The other options do not accurately reflect what a watt measures, as they pertain to different aspects of electrical systems such as duration, voltage, or total energy stored.
