Question 1
What is the formula for calculating collector current (I_C)?
- I_C = I_B / Ξ²
- I_C = I_B * Ξ²
- I_C = Ξ² / I_B
π‘ Hint: Remember the interdependency of collector and base currents.
Question 2
True or False: Coupling capacitors are used to allow DC signal transfer in amplifiers.
- True
- False
π‘ Hint: Consider the role of AC vs. DC in signal processing.

Challenge Problems
Push your limits with challenges.
Question 1
Design a common emitter amplifier with a target gain of 100. If V_CC is 15V, and we choose a collector resistor drop of 7V, what are the values for R_C and bias resistors?
π‘ Hint: Start by calculating the necessary I_C from the desired voltage gain.
Question 2
Given a transistor with Ξ² = 120 and I_C = 2 mA, what is the required I_B? Additionally, determine the voltage drop across a 4.7KΞ© collector resistor.
π‘ Hint: Use Ohm's law and the collector current to find resistance values you're interested in.
