Q: Which of the following describes the behavior of a Zener diode?

Solution: A Zener diode is designed to maintain a constant voltage across it when reverse-biased, allowing it to regulate voltage.

Steps: 5

Step 1: Understand what a Zener diode is. It is a special type of diode that allows current to flow in the reverse direction when a certain voltage is reached.
Step 2: Learn about reverse biasing. When a Zener diode is reverse-biased, it means that the voltage is applied in the opposite direction to normal current flow.
Step 3: Know the purpose of a Zener diode. It is used to keep the voltage across it constant, even if the input voltage changes.
Step 4: Recognize that when the reverse voltage exceeds a specific value (called the Zener voltage), the diode starts conducting in reverse, maintaining that voltage level.
Step 5: Conclude that the Zener diode is used for voltage regulation in circuits, ensuring that the voltage remains stable.
