Electrical power is measured in what unit?

Electrical power is measured in watts. This unit quantifies the rate at which electrical energy is transferred by an electric circuit. One watt is defined as one joule per second and represents a power level where one ampere of current flows through an electric potential difference of one volt.

Understanding watts is crucial in maintenance work as it helps determine the capacity of electrical devices and systems. When assessing the power requirements for appliances, lighting, or machinery, knowing the wattage allows a maintenance worker to ensure that the electrical system can handle the load without overloading or causing inefficiencies.

In contrast, other units mentioned serve different purposes in the realm of electricity. Amperes, for instance, measure electrical current, volts measure electrical potential or voltage, and ohms measure resistance. Each of these measurements interacts within the electrical system, but when it comes to understanding power specifically, watts is the correct unit of measurement.
