What is the measurement unit for a wattmeter?

Explanation:
A wattmeter is designed to measure electrical power in a circuit, and the appropriate unit for this measurement is watts. Watts quantify the rate at which energy is consumed or produced in an electrical system, making it the standard unit used in the context of electrical power measurement. Understanding this enables professionals to determine energy usage and efficiency in various electrical devices and systems. The other choices represent different electrical measurements: ohms measure resistance, volts measure electrical potential difference, and hertz measure frequency. Each of these units serves a distinct purpose in the field of electrical mechanics, but none are suitable for measuring electrical power, which is specifically expressed in watts.
