If the output of a voltage regulator varies from 20 to 19.8 V when the line voltage varies over its specified range, the load regulation is
A)2%.
B)5%.
C)0.
D)1%.

Question

Quizplus · Accepted Answer

Load regulation is calculated as the change in output voltage divided by the nominal output voltage, expressed as a percentage. Here, the change is 0.2 V (20 - 19.8), and the nominal output is 20 V. So, (0.2/20) * 100% = 1%.
