👉 A turnmeter is a device used to measure and control electrical energy consumption in an electric circuit. It consists of a voltage regulator, which converts the input voltage into a lower frequency output voltage, and a resistance component, which limits the flow of current through the circuit. Turnmeters are commonly used in residential and commercial applications for measuring power usage, such as lighting or appliances, as well as in industrial settings for monitoring energy consumption in power plants. They can also be used to control electrical loads on
