question:
Passage: The rate at which a device changes electric current to another form of energy is called electric power . The SI unit of powerincluding electric poweris the watt. A watt equals 1 joule of energy per second. High wattages are often expressed in kilowatts, where 1 kilowatt equals 1000 watts. The power of an electric device, such as a microwave, can be calculated if you know the current and voltage of the circuit. This equation shows how power, current, and voltage are related:. Answer: electric power
answer:
What term describes the rate at which a device changes electric current to another form of energy?
