Challenge Problems
Push your limits with advanced challenges
An LCR circuit has R = 25Ω, L = 0.4H, and C = 10μF. Calculate the resonant frequency and the impedance at this frequency.
💡 Hint: Recall that at resonance, XC = XL.
Design an LCR circuit that resonates at 60Hz. If you choose L = 50mH, what should C be?
💡 Hint: Make sure to convert everything into SI units for consistency.
