Question 1 of 10
What is the primary function of a diode?
Diodes are designed to conduct current in one direction and block it in the opposite direction.
Question 2 of 10
What does PN junction stand for?
The PN junction is formed by joining P-type and N-type semiconductor materials.
Question 3 of 10
Which terminal of a diode is typically indicated by a line or bar?
The cathode is usually indicated by a line or bar to identify its polarity.
Question 4 of 10
What type of charge carriers are dominant in P-type semiconductor materials?
P-type materials have an abundance of holes, which act as positive charge carriers.
Question 5 of 10
What type of charge carriers are dominant in N-type semiconductor materials?
N-type materials are characterized by a majority of free electrons, which carry a negative charge.
Question 6 of 10
What happens when P-type and N-type materials are joined?
The joining forms a depletion region due to the recombination of electrons and holes.
Question 7 of 10
What is the depletion region?
The depletion region is devoid of free charge carriers, creating an insulating layer.
Question 8 of 10
What is the potential barrier (VD) in a PN junction?
The potential barrier opposes the flow of charge carriers across the junction.
Question 9 of 10
What is the name for a diode?
A diode is also known as a rectifier, because it 'rectifies' AC signals to DC
Question 10 of 10
What are the two terminals of a diode?
The two terminals of a diode are Anode and Cathode.
