Challenge Problems
Push your limits with challenges.
Question 1
Design a common emitter amplifier circuit. Given a desired collector current of 2 mA and a β of 150, what must the base current be? Assume V_BE(on) is 0.7 V.
💡 Hint: Remember to use the relationship I_c = β × I_b.
Question 2
A circuit has a load resistor of 1 kΩ and experiences a collector current of 10 mA. If the supply voltage is 15 V, calculate the collector voltage and determine the power dissipated across the load.
💡 Hint: Use Ohm's law to relate current to voltage across the load.
