📝 II. Sample Exam Questions

Below are some typical questions based on the exam pattern and textbook content. These cover core topics like analog/digital circuits, semiconductor devices, and practical applications.

1. Multiple-Choice Questions

  1. What is the relationship between RMS voltage and maximum voltage for a sine wave?
    A. \( V_{\text{RMS}} = V_{\text{max}} \)
    B. \( V_{\text{RMS}} = 0.707 \times V_{\text{max}} \)
    C. \( V_{\text{RMS}} = 1.414 \times V_{\text{max}} \)
    D. \( V_{\text{RMS}} = 0.5 \times V_{\text{max}} \)
    Answer: B 【turn0search14】

  2. In a series DC circuit with a 3Ω and 5Ω resistor carrying 10A, what is the total voltage?
    A. 10V
    B. 50V
    C. 80V
    D. 100V
    Answer: C (Calculation: \( V = I \times R = 10A \times (3Ω + 5Ω) = 80V \)) 【turn0search16】

2. Calculation and Analysis

  1. Amplifier Circuit:
    Given a BJT amplifier with \( \beta = 100 \), \( R_C = 2.2kΩ \), and \( V_{CC} = 12V \), calculate the collector current \( I_C \) and voltage gain \( A_V \) if the input resistance \( R_{in} = 1kΩ \).

  2. Op-Amp Application:
    Design an inverting amplifier with a gain of -10 using an ideal op-amp. Choose \( R_{in} = 1kΩ \) and determine \( R_f \).

3. Conceptual Questions

  1. Semiconductor Devices:
    Explain the difference between enhancement-mode and depletion-mode MOSFETs.

  2. Digital Circuits:
    Describe the advantages of CMOS logic over TTL logic in terms of power consumption and noise immunity.

4. Practical Problem-Solving

  1. Oscillator Circuit:
    Draw a Colpitts oscillator circuit and explain how the feedback network generates sustained oscillations.

  2. Power Supply:
    Design a simple 5V regulated power supply using a 7805 IC. Include the required components and calculate the minimum input voltage.

🎯 III. Key Topics for Exam Preparation

Based on the textbook and past exams, focus on these areas:
