Challenge Problems
Push your limits with challenges.
Question 1
In a common emitter circuit, if the base current is 20 μA and β = 150, what is the collector current? If the load resistance is 1kΩ, calculate the output voltage if the supply voltage is 10V.
💡 Hint: Use the relationship between Ib, Ic, and load resistance effectively.
Question 2
Discuss the effects on the output voltage if the load resistance is decreased in a common emitter amplifier and explain why this happens.
💡 Hint: Consider Ohm's law and the impact on voltage as current increases.
