pn junction diode Quiz
easy
5 Questions
Question 1 of 5
A p-n junction diode is formed by joining which two semiconductor materials?
A p-n junction requires p-type and n-type semiconductor materials.
Question 2 of 5
What happens to the depletion region width when a p-n junction diode is reverse biased?
Reverse bias widens the depletion region by repelling the majority carriers away from the junction.
Question 3 of 5
In a forward-biased p-n junction diode, the current is primarily due to:
Forward bias allows majority carriers to overcome the depletion region.
Question 4 of 5
What is the primary function of a p-n junction diode?
A diode's switching behavior (conducting in one direction and blocking in the other) makes it suitable for switching applications.
Question 5 of 5
The voltage at which a diode begins to conduct significantly in the forward direction is called:
The forward voltage drop (or threshold voltage) is the voltage required for a diode to conduct significantly.
