Lesson 5 Zener Diodes Quiz

What is the main benefit of Zener diodes?

• They allow current to flow bidirectionally

• They are heavily doped than ordinary diodes

• They can be used for voltage regulation applications

• They have a set reverse breakdown voltage

What is a zener diode?

• A zener diode is a type of diode that is used to store electrical energy.

• A zener diode is a type of diode that only allows current to flow in one direction.

• A zener diode is a type of diode that allows current to flow in the reverse direction when a certain voltage threshold is reached.

• A zener diode is a type of diode that is used to amplify electrical signals.

What is the key difference between Zener diodes and conventional diodes?

• Zener diodes conduct in both forward and reverse bias condition

• Zener diodes have a higher doping intensity

• Zener diodes have a bias turn-on voltage of between 0.3 and 0.7V

• Zener diodes have a constant voltage drop across the diode

What are the two main characteristics of a zener diode?

• Ability to conduct current in both forward and reverse directions and ability to maintain a constant voltage

• Inability to conduct current in both forward and reverse directions and inability to maintain a constant voltage

• Ability to conduct current in only forward direction and ability to maintain a constant voltage

• Ability to conduct current in both forward and reverse directions and inability to maintain a constant voltage

What happens when a Zener diode is connected in the reverse mode?

• The diode gets damaged

• There is a small leakage current flow

• The diode stops conducting

• There is a large current flowing through the diode

What is the purpose of the zener diode in a circuit?

• To reduce resistance

• To regulate voltage

• To amplify current

• To increase capacitance

What is the characteristic of a Zener diode when the current value flowing through it changes?

• The voltage remains almost constant

• The voltage increases proportionally

• The voltage fluctuates randomly

• The voltage decreases proportionally

What is the breakdown voltage of a zener diode?

• The breakdown voltage of a zener diode is the average voltage at which the diode operates in the forward biased direction.

• The breakdown voltage of a zener diode is the voltage at which the diode stops conducting in the reverse biased direction.

• The breakdown voltage of a zener diode is the maximum voltage at which the diode starts conducting in the forward biased direction.

• The breakdown voltage of a zener diode is the minimum voltage at which the diode starts conducting in the reverse biased direction.

What is the purpose of connecting multiple Zener diodes in series?

• To decrease the breakdown voltage

• To increase the current flowing through the diodes

• To reduce the leakage current

• To achieve a particular Zener voltage

How does a zener diode behave in the forward bias?

• It blocks current flow in the forward bias.

• It allows current to flow from the anode to the cathode when the voltage across it is greater than the forward voltage drop.

• It allows current to flow from the cathode to the anode when the voltage across it is greater than the forward voltage drop.

• It behaves like a regular diode in the forward bias.
