Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

An RL circuit with R = 12Ω and L = 80 mH: What is the time constant and how long until the current is 2.5 A if the final current is 5 A?

💡 Hint: Use the step response formula and play with the exponential equation.

Challenge 2 Hard

Given an RL circuit at equilibrium with a final current of 3 A, calculate what happens if the circuit is suddenly switched off. How long will it take to drop below 0.1 A?

💡 Hint: Utilize the decay formula and evaluate the parameters.
