Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a series resonant circuit with a target resonant frequency of 10 kHz. Given a capacitor of value 100 nF, calculate the required inductance.

💡 Hint: Ensure your units are consistent when solving.

Challenge 2 Hard

For a parallel resonant circuit with the desired conditions of R = 50 Ω, L = 0.1 H, and C = 500 µF, evaluate the quality factor Q. Discuss the implications of a low vs high Q.

💡 Hint: Think about the implications on bandwidth based on Q value.
