Challenge Problems
Push your limits with challenges.
Question 1
For a circuit using C1 = 5 µF, C2 = 20 pF, and a load capacitance of 2 µF, calculate the combined output capacitance and discuss its impact on frequency.
💡 Hint: Remember to add only the relevant capacitances affecting the output.
Question 2
If you alter C3 in the input section from 1 µF to 10 µF while keeping C4 constant at 50 pF, how does this impact the overall frequency response?
💡 Hint: Keep in mind how reactance and frequency are interrelated!
