Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a parallel RL circuit with a resistor of 75Ω and an inductance of 0.3 H connected to a 120V AC source at 60Hz. Calculate the total current and explain how the impedance angle affects total current.

💡 Hint: Think about calculating angles and combining complex numbers for admittance.

Challenge 2 Hard

A 40Ω resistor and a 0.5 H inductor are in parallel across a 240V source at a frequency of 50Hz. Determine the total admittance and total current along with phase relationships.

💡 Hint: Focus on understanding impedance and current relationships within AC circuits.
