V/R has various meanings in the Auto category. Discover the full forms, definitions, and usage contexts of V/R in Auto.
A circuit which is connected between the power source and a load, which provides a constant voltage despite variations in input voltage or output load. Voltage regulators control the output voltage, eliminating voltage sags and swells in the input voltage that last from 15 milliseconds to one-half second. They are typically relatively inexpensive feedback controlled transformers and the more expensive ferroresonant transformer.
