Challenge Problems
Push your limits with challenges.
Question 1
You have a common base amplifier with a specified coupling capacitor. If the input voltage is 1V and the gain calculated is 10.31, what is the expected output voltage if the capacitor is removed?
π‘ Hint: Consider the effect of voltage gain reduction discussed in class.
Question 2
Analyze a circuit where input resistance without the coupling capacitor is given as 580 kΞ©. If you were to include a gain, how would that change based on the gain formula you learned?
π‘ Hint: Revisit how changes in configuration alter resistance measurements in circuits.
