Question 1 of 10
What are the two terminals of a diode called?
Diodes have an Anode (+) and a Cathode (-).
Question 2 of 10
Which type of semiconductor material has an abundance of holes?
P-type semiconductors are created by doping with trivalent impurities, creating an abundance of holes.
Question 3 of 10
What is the region formed at the junction of P-type and N-type semiconductors in a diode?
The depletion region is formed due to the diffusion of charge carriers across the PN junction.
Question 4 of 10
In which bias condition does a diode block current flow?
In reverse bias, the diode acts like an open circuit, blocking current flow.
Question 5 of 10
What type of impurities are added to create a P-type semiconductor?
Trivalent impurities like boron are added to create P-type semiconductors.
Question 6 of 10
What happens to the depletion region width in reverse bias?
In reverse bias, the depletion region widens, increasing the resistance to current flow.
Question 7 of 10
What is the term for the small current that flows through a diode in reverse bias?
Reverse saturation current is caused by the flow of minority carriers.
Question 8 of 10
What is the primary function of a diode?
A diode's primary function is to permit current flow in a single direction.
Question 9 of 10
What happens when a diode reaches its reverse breakdown voltage?
At reverse breakdown voltage, the diode fails and allows a significant reverse current.
Question 10 of 10
Which material is most commonly used for creating diodes?
Silicon is the most common semiconductor material used in diodes.
