A wattmeter is an instrument used to measure the electrical power in watts of an electrical circuit. It can measure both AC and DC power, making it essential for various applications, including energy monitoring, load analysis, and efficiency testing in electrical systems. Wattmeters help in diagnosing issues in electrical circuits and optimizing energy consumption for residential, commercial, and industrial setups. Additionally, they are useful in research and development to evaluate the performance of electrical devices.
