10 Questions
Question 1 of 10
What is the primary difference between a normal diode and a Zener diode regarding current flow?
Zener diodes are specifically designed to allow current flow in the reverse direction when the Zener breakdown voltage is reached.
Question 2 of 10
What happens when the applied reverse voltage is below the Zener breakdown voltage?
When the voltage is below the Zener breakdown voltage (Vz), the diode remains in a non-conducting state.
Question 3 of 10
What is the primary purpose of a Zener diode in an electronic circuit?
Zener diodes are widely used for voltage regulation because they maintain a stable output voltage across a load.
Question 4 of 10
In which mode of operation is a Zener diode specifically designed to function?
Unlike normal diodes, Zener diodes are specifically designed to operate in reverse bias mode.
Question 5 of 10
What does the term 'Zener breakdown voltage' (Vz) represent?
Vz is the fixed voltage value at which the Zener diode begins to conduct in the reverse direction.
Question 6 of 10
How does a Zener diode respond to changes in input voltage while regulating?
The Zener diode maintains a stable output voltage even if the input voltage changes, provided it is above the breakdown threshold.
Question 7 of 10
Which of the following is a listed application for a Zener diode?
The article explicitly lists overvoltage protection as a key application for Zener diodes.
Question 8 of 10
What happens to the voltage across the load when the Zener diode reaches its breakdown voltage?
Once the Zener voltage is reached, the diode conducts in reverse, maintaining a stable voltage across the load.
Question 9 of 10
Besides voltage regulation and protection, what is another application mentioned for Zener diodes?
The article identifies waveform clipping and shaping as a standard application for Zener diodes.
Question 10 of 10
If a Zener diode has a Vz of 5.6V, what happens when the supply voltage increases beyond 5.6V?
The Zener diode begins to conduct at its rated Vz, ensuring the voltage across it remains stable.
