Module 4 Electronic Fundamentals Practice Questions - UK CAA Part-66 AME Module 4 - Electronic Fundamentals Exam - Module 4 Electronic Fundamentals Practice Questions - UK CAA Part-66 AME Module 4

Question 1

In semiconductor physics, what effect does doping pure silicon with a pentavalent element such as phosphorus or arsenic produce?

Creates P-type semiconductor material with holes as majority charge carriers Creates N-type semiconductor material with free electrons as majority charge carriers Eliminates the depletion layer completely under all bias conditions Increases the intrinsic energy band gap between valence and conduction bands

Correct Answer:

Creates N-type semiconductor material with free electrons as majority charge carriers

Question 2

What is the typical potential barrier voltage formed across an unbiased silicon PN junction at room temperature (25°C)?

0.1 to 0.2 V 0.3 V 0.6 to 0.7 V 1.2 to 1.4 V

Correct Answer:

0.6 to 0.7 V

Question 3

What happens to the depletion region width and internal resistance of a PN junction diode when it is reverse-biased?

Depletion region narrows and internal resistance decreases Depletion region widens and internal resistance increases significantly Depletion region remains unchanged while current increases linearly Depletion region collapses completely enabling heavy majority carrier drift

Correct Answer:

Depletion region widens and internal resistance increases significantly

Question 4

How does a Zener diode maintain a constant voltage across its terminals when connected in a voltage regulator circuit?

By operating in its forward conduction region above 0.7 V By operating in its reverse breakdown region above its specified Zener voltage By varying its internal capacitance in proportion to input frequency By acting as an open circuit whenever input voltage rises

Correct Answer:

By operating in its reverse breakdown region above its specified Zener voltage

Question 5

A simple Zener voltage regulator operates from a 15 V DC supply to provide a regulated 9.1 V output to a load. If the total circuit current flowing through the series resistor R_S is 25 mA, what is the required value of R_S?

100 Ω 236 Ω 364 Ω 600 Ω

Correct Answer:

236 Ω
