👉 A variocoupler is a device used to connect two or more coils in a circuit, thereby allowing for the control of voltage or current across those coils. Variocouplers are commonly found in electronic circuits and can be used to adjust the voltage output of an AC generator, as well as to control the flow of current through a transformer or other electrical components. They allow for precise control over the power supply and can also be used in conjunction with other devices to create more complex circuit designs.
