wattmõõtur

A wattmõõtur, also known as a power meter, is a device that measures the amount of electrical power being consumed by a circuit or device. This measurement is typically expressed in watts (W). Wattmõõturs are essential tools for understanding energy usage, identifying inefficiencies, and ensuring the proper operation of electrical systems. They can be found in various forms, from simple household plug-in units to sophisticated industrial equipment. The fundamental principle behind most wattmõõturs involves measuring both the voltage across a circuit and the current flowing through it. By multiplying these two values, the instantaneous power can be calculated. Some wattmõõturs also measure power factor, which is the ratio of real power to apparent power, providing a more complete picture of energy consumption. These devices are used in a wide range of applications, including energy audits for homes and businesses, troubleshooting electrical problems, monitoring the performance of appliances, and in scientific research. The data provided by a wattmõõtur can help users make informed decisions about reducing energy consumption and lowering electricity bills.
