Industrial Instrumentation Exam Summary

General Structure of the Exam

The exam is divided into two sections: Section I (Multiple Choice Items, 20% of total marks) and Section II (Essay-Type Items, 80% of total marks). Students must follow specific instructions for each section and submit the answer sheet along with their essay responses.

Section I: Multiple Choice Items

• Consists of 20 questions with four response options each.
• Students must select the best option by circling the corresponding letter.
• Instructions for changing a response include marking an "X" over the original choice and circling the new option.
• Key Concepts include:
  • Common-drain JFET amplifier characteristics.
  • SCR behavior in AC circuits.
  • Amplifier configurations such as non-inverting and class B amplifiers.

Section II: Essay-Type Items

• Four questions must be answered. Each question varies in mark allocation, including definitions, sketches, and explanations.
• Key topics include:
  • PIV (Peak Inverse Voltage): Definition and importance.
  • Doping: Explanation of semiconductor doping and its types (N-type and P-type).
  • Transistor operation: Analysis of BJT and JFET switches with advantages.
  • Feedback mechanisms in amplifiers, oscillators, and the advantages of negative feedback.
• Example calculations and circuit analyses are required for full marks in some questions.
