The correct formula for Voltage Regulation is:
- VR = (Vnl + Vfl)/ Vfl
- VR = (Vnl – Vfl)/ Vfl
- VR = (Vfl + Vnl)/ Vfl
- VR = (Vfl – Vnl)/ Vfl
Correct answer: VR = (Vnl – Vfl)/ Vfl
Voltage Regulation Formula
Voltage regulation is the measure of the ability of an electrical machine to keep the constant voltage at terminals with load variation. It is mathematically expressed by the following formula:
