Challenge Problems
Push your limits with challenges.
Question 1
Calculate the total impedance for a series RLC circuit at different frequencies (1000 rad/s, 5000 rad/s) with R = 20Ξ©, L = 0.01H, and C = 100ΞΌF. Discuss how impedance changes.
π‘ Hint: Calculate |Z| with the magnitude formula; analyze how frequency affects reactance.
Question 2
Discuss the implications of operating an RLC circuit at a frequency far from resonance. How does this affect the impedance and current?
π‘ Hint: Think about impedance's role in limiting current and how resonance balances it.
