Challenge Problems
Push your limits with challenges.
Question 1
A common collector amplifier has an output resistance of 50 ohms. What happens if you change the load to 150 ohms?
💡 Hint: Apply voltage division principles to find new output conditions.
Question 2
Analyze how increasing the collector resistance from 100 ohms to 500 ohms affects voltage gain and output resistance.
💡 Hint: Evaluate the relationship between voltage gain and change in output resistance.
