Challenge Problems
Push your limits with challenges.
Question 1
Consider a series LCR circuit with R = 10Ξ©, L = 30 mH, and C = 100Β΅F. Calculate the impedance at resonance and determine the resonant frequency.
π‘ Hint: Use resonance equations to find relevant parameters.
Question 2
In an LCR circuit, if the inductive reactance is 15Ξ©, and the capacitive reactance is 10Ξ©, calculate the phase angle and describe the behavior of the circuit.
π‘ Hint: Start with the phase angle formula and plug in given values accordingly.
