Question 1 of 15
What is formed when a p-type semiconductor is joined with an n-type semiconductor?
A PN junction diode is created by joining a p-type and an n-type semiconductor.
Question 2 of 15
What type of charge carriers are dominant in a p-type semiconductor?
P-type semiconductors have an abundance of holes.
Question 3 of 15
What type of charge carriers are dominant in an n-type semiconductor?
N-type semiconductors have an abundance of electrons.
Question 4 of 15
In which direction does a diode allow current to flow ideally?
A diode acts as a one-way switch.
Question 5 of 15
What happens to the depletion region in a diode under reverse bias?
Reverse bias causes the depletion region to widen, blocking current.
Question 6 of 15
What happens to the depletion region in a diode under forward bias?
Forward bias causes the depletion region to shrink, allowing current.
Question 7 of 15
In reverse bias, what terminal is connected to the P-side?
In reverse bias, the negative terminal is connected to the P-side.
Question 8 of 15
In forward bias, what terminal is connected to the P-side?
In forward bias, the positive terminal is connected to the P-side.
Question 9 of 15
What is the primary function of a diode?
Diodes act as a one-way switch, allowing current flow in only one direction.
Question 10 of 15
What type of current flows through a diode in forward bias (ideally)?
In forward bias, current flows freely.
Question 11 of 15
What type of current flows through a diode in reverse bias (ideally)?
In reverse bias, very little current flows (leakage current).
Question 12 of 15
What happens to the charge carriers in forward bias?
Electrons and holes move towards the junction under forward bias.
Question 13 of 15
Which of the following best describes a depletion region?
The depletion region is depleted of free charge carriers.
Question 14 of 15
What is the main component of a PN Junction?
A PN junction is formed by combining P-type and N-type semiconductors.
Question 15 of 15
What is the effect of leakage current in a diode?
Leakage current is a small current that flows through the diode in reverse bias.
