Challenge Problems
Push your limits with challenges.
Question 1
A series RLC circuit has R = 60Ω, L = 0.2H, and C = 50μF. Calculate the resonant frequency and the total impedance at 60Hz.
💡 Hint: Use the resonant frequency formula, then apply impedance calculations.
Question 2
For a circuit with R = 30Ω, L = 0.2H, and C = 100μF, find the phase difference and current using 120V AC supply.
💡 Hint: Break the problem into systematic steps: find XL and XC first.
