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 that Zener diodes are used in electronic circuits to maintain a constant voltage level.
Step 3: Recognize that when the voltage exceeds a specific value (called the Zener voltage), the Zener diode starts conducting in reverse, helping to regulate the voltage.
Step 4: Conclude that the primary use of a Zener diode is to keep the voltage stable in various electronic applications.
