Given the following values: a collector current (I_C) of 3 mA, a collector-emitter voltage (V_CE) of 7 V, R_C = 1.5kΩ, and the load resistance = 10 kΩ, determine the mid-band gain.
💡 Hint: Perform each calculation step carefully, ensuring you understand how to apply the formulas.
Discuss how varying the V_CC affects the Q-point and mid-band performance of the amplifier, including potential distortion effects.
💡 Hint: Consider what happens to both the voltage and current in your amplifier as V_CC changes.
