What is a watt?

A watt is defined as a unit of measure for electrical power. It quantifies the rate at which energy is used or generated in an electrical circuit. One watt is equivalent to one joule of energy per second. Understanding this concept is fundamental in the field of electricity and utilities because it helps to determine how much power devices consume and how systems are designed to handle electricity. The power generated by electrical appliances and systems is typically measured in watts, making it crucial for energy management and efficiency assessments in utility marketing.

The other options represent different concepts related to electricity. Voltage is measured in volts, which indicates the electrical potential difference. Current is measured in amperes (amps) and represents the flow of electric charge. Resistance, on the other hand, is measured in ohms and signifies how much a material opposes the flow of electric current. Each of these measurements plays a role in the overarching framework of electrical systems, but wattage specifically pertains to power.
