### Transcription for Educational Website #### Electrical Parameter Summary This table provides a summary of various DC and AC electrical parameters typically used in electronic circuit analysis. **DC Values:** - **\( V_C \):** Collector Voltage - **\( V_B \):** Base Voltage - **\( V_E \):** Emitter Voltage - **\( V_{CE} \):** Collector-Emitter Voltage - **\( I_C \):** Collector Current **AC Values:** - **\( V_{in} \):** Input Voltage - **\( I_{in} \):** Input Current - **\( R_{in} \):** Input Resistance - **\( V_{out} \):** Output Voltage - **\( I_{out} \):** Output Current - **\( A_V \):** Voltage Gain - **\( A_i \):** Current Gain - **\( A_p \):** Power Gain ### Explanation of Parameters - **DC Values** are concerned with the direct current (steady-state) characteristics of a circuit, particularly in transistor circuits, where understanding the voltages and currents at specific points is crucial for biasing and operating point analysis. - **AC Values** focus on the alternating current characteristics where signals vary with time. Parameters like input/output voltage and current, and various gains are essential for analyzing how signals are amplified in circuits. This table should serve as a reference for students and professionals to quickly identify key parameters in circuit design and analysis.

**Part I: Common Emitter Amplifier** **Circuit Diagram:** The diagram shows a common emitter amplifier circuit including components such as resistors, capacitors, and a transistor. Key elements are: - \( V_{CC} \): Power supply voltage. - \( R_C, R_X, R_1, R_2, R_{E1}, R_{E2}, R_g \): Resistors. - \( C_E \): Emitter bypass capacitor. - \( V_{in} \): Input AC voltage source. **Given Circuit Values:** - \( V_{CC} = 20V \) - \( R_C = 15k\Omega \) - \( R_X = 22k\Omega \) - \( R_1 = 220k\Omega \) - \( R_2 = 56k\Omega \) - \( R_{E1} = 300\Omega \) - \( R_{E2} = 3.9k\Omega \) - \( R_g = 100k\Omega \) **Instructions:** 1. Calculate DC Values and record the results. 2. Calculate AC Values and record the results. 3. Measure \( V_C, V_B, \) and \( V_E \). Calculate \( V_{CE} \) and record all values. 4. Determine the measured value of \( I_C \) using: \[ I_C = \frac{V_{CC} - V_C}{R_C} \] **Formulas:** - **Emitter Resistor Calculation:** \[ r'_e = \frac{25mV}{I_E} \] - **Voltage Gain:** \[ A_v = \frac{R_C \parallel R_2}{r'_e + R_{E1}} \] - **Input Resistance:** \[ R_{in(total)} = R_1 \parallel R_2 \parallel \beta_{ac}(r'_e + R_{E1}) \] Use these steps and formulas to analyze the common emitter amplifier circuit systematically. Ensure all measurements are accurate and follow proper procedures for calculations and recordings in the provided sections.
