What is the most useful characteristic of a Zener diode?
Pick an answer to check it.
Answer: B. A constant voltage drop under conditions of varying current
A Zener diode holds a nearly constant voltage across itself even as the current through it changes. That makes it useful as a voltage reference or simple regulator.
Tip: Zener = steady voltage.
