Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

An RL series circuit with R = 50Ω and XL = 70Ω is connected to a 240V supply. Calculate the total impedance, current, and verification with voltage drops.

💡 Hint: Break down calculations for impedance, then apply Ohm's law systematically.

Challenge 2 Hard

Design a similar RL circuit to operate at a specific current of 5A at a voltage of 120V. Calculate R and XL, ensuring the phase angle meets standard applications.

💡 Hint: Explore R and XL dimensions to fit within limits defined by system constraints.
