Three examples from the live 100-question bank. Answers appear after attempting them in practice mode.
Example 1 · difficulty 1/5
A pure silicon crystal is doped with a trace amount of arsenic. The resulting material is best described as:
- A. a p-type semiconductor because arsenic has five valence electrons
- B. an intrinsic semiconductor, since silicon remains tetravalent
- C. an n-type semiconductor in which electrons are the majority carriers
- D. a p-type semiconductor in which holes are the majority carriers
Example 2 · difficulty 1/5
As the temperature of an intrinsic semiconductor is lowered towards 0 K, its electrical behaviour most closely resembles that of a(n):
- A. metallic conductor
- B. perfect insulator
- C. superconductor
- D. doped semiconductor with a fixed carrier concentration
Example 3 · difficulty 2/5
The primary of a centre-tapped full-wave rectifier is supplied with a 50 Hz sinusoidal AC voltage. The fundamental frequency of the ripple present in the rectified output is:
- A. 50 Hz
- B. 200 Hz
- C. 25 Hz
- D. 100 Hz
