Calculate the voltage regulation in the synchronous machine if the no-load voltage is 12 V and the full load voltage is 15V.

Calculate the voltage regulation in the synchronous machine if the no-load voltage is 12 V and the full load voltage is 15V. Correct Answer -20%

Voltage regulation is defined as the fluctuation in the load voltage when the load is varied from no-load to full load. V.R(%) = (No-load voltage-Full load voltage) ÷ Full load voltage=12-15÷15 = -20%.
