Challenge Problems
Push your limits with advanced challenges
A common emitter amplifier has a collector current of 2.5 mA instead of 2 mA. How does this affect the output voltage if the early voltage is still 100 V?
💡 Hint: Calculate the effect of the output resistance.
Calculate the new base current if the beta increases to 150 while keeping the collector current at 2 mA.
💡 Hint: Remember that changes in beta affect the calculations.
