ANSWERS WITH RATIONALES
AMS 116 UNIT 4 EXAM - Complete Questions 1-300
Question 1
A "hole" in a semiconductor material has a _____ charge.
A) Negative
B) Positive
C) Neutral
D) Alternating
Answer: B
A "hole" is the absence of an electron in a semiconductor crystal lattice and behaves as a
positive charge carrier.
Question 2
A semiconductor is made into N-type or P-type through a process called _____.

A) Diffusion
B) Doping
C) Ionization
D) Rectification
Answer: B
Doping is the process of adding impurities to a semiconductor to change its electrical properties
and create either N-type or P-type material.
Question 3
Two materials that are commonly used as semiconductors are _____ and _____.
A) Copper and Silver
B) Germanium and Silicon
C) Aluminum and Gold
D) Carbon and Tin
Answer: B
Germanium and silicon are the most commonly used semiconductor materials in electronic
components due to their electrical properties.

Question 4
The "anode" of a diode is made of ______ semiconductor material.
A) N-type
B) P-type
C) Intrinsic
D) Extrinsic
Answer: B
The anode is the positive terminal of a diode and is made of P-type semiconductor material.
Question 5
Zener diodes will conduct in the reverse direction when a reverse voltage is at or above a
specific value. (True/False)
A) True
B) False

Answer: A
Zener diodes are designed to conduct in the reverse direction at a specific breakdown voltage,
making them useful for voltage regulation.
Question 6
When a diode is forward biased, the negative potential of the battery ______ the electrons in
the _______ material.
A) Attracts / P-type
B) Repels / N-type
C) Attracts / N-type
D) Repels / P-type
Answer: B
The negative potential repels electrons in the N-type material, pushing them toward the
junction and allowing current flow.
