Challenge Problems
Push your limits with challenges.
Question 1
Design a common emitter amplifier circuit with given specifications: V_CC = 15V, load resistor R_C = 2kΩ, and beta (β) = 200. Determine the base current required to achieve an output current (I_C) of 10 mA.
💡 Hint: Use the known relationships of collector and base currents.
Question 2
If the collector current of a BJT is measured at 5 mA, and it has a beta of 50, calculate the base current and the corresponding V_CE if the supply voltage V_CC is 12V and R_C is 1kΩ.
💡 Hint: Look at how base and collector currents relate to each other.
