The formula to calculate the Voltage Regulation (VR) is:
\[ VR = \frac{V1 - V2}{V1} \]
Where:
Voltage regulation measures a system’s ability to provide constant voltage over a wide range of loads. In actual physical systems, this is performed by a voltage regulator.
Consider an example where:
Using the formula to calculate the Voltage Regulation:
\[ VR = \frac{120 - 115}{120} = 0.0417 \text{ or } 4.17\% \]
This means that the voltage regulation for this example is 4.17%.
