If the source voltage increases in a simple zener regulator, ________.
A)the voltage across the zener increases
B)the voltage across the series resistor decreases
C)the load current increases
D)the zener current increases

Question

Quizplus · Accepted Answer

The zener diode maintains a constant voltage across it, so if the source voltage increases, the excess voltage is dropped across the series resistor, increasing the zener current.
