Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a parallel RLC circuit that resonates at 60 Hz. If you choose a 100 μF capacitor, what inductance is necessary?

💡 Hint: Use the resonance formula and rearrange it for inductance.

Challenge 2 Hard

Calculate the circulating current in a parallel circuit with a 50 Ω resistor, a 0.1 H inductor, and a 20 μF capacitor at resonance where the applied voltage is 120 V.

💡 Hint: Keep in mind to calculate based on the power factor behavior and Q.
