How does electric power work?
Understand the Problem
The question is asking for an explanation of how electric power operates, including its fundamental principles and concepts such as generation, transmission, and usage.
Answer
Electric power is the rate of transfer of electrical energy in a circuit, measured in watts.
Electric power is the rate at which electrical energy is transferred through an electrical circuit. It is measured in watts, and relies on the movement of electrons through a closed circuit to deliver power to devices or systems.
